    ABSTRACT: A series of three new boron-dipyrromethenes bringing different functionalized triphenylamine donor Bodipy-TPA-R (R = BI, BH-OH, BH-COOH) (1-3) together with the reference compound Bodipy-TPA (0), have been synthesized and structurally characterized. Due to their same less electronic coupling between the triphenylamine donor and Bodipy acceptor in ground state and in particular the twisted intramolecular charge transfer (TICT) between them in excited state, these functionalized Bodipy derivatives exhibit similar optical properties in solution but not in the solid state owing to their differently intermolecular interaction and molecular packing associated with the diverse triphenylamine-modification. The lack of effective face-to-face π-π stacking interaction between Bodipy luminophores in crystalline states of 0 and 3, in combination with the restriction of the twisting motion and charge transfer between their triphenylamine moiety and Bodipy framework, results in the obvious aggregation- (AIE) and crystallization-induced emission (CIE) effect, with the absolute fluorescent quantum yield (ℙ) as high as 19.47% and 12.30% for single crystals of 0 and 3, respectively. In good contrast, despite the same complete restriction of the functionalized triphenylamine donor around Bodipy acceptor, the presence of partial overlapping face-to-face π-π interaction between two parallel C9BN2 fluorophores leads to very low ℙ being 1.37% and 3.40% for the single crystals of 1 and 2 as well as the negligible AIE effect. Moreover, the CIE-active red-emission for 3 can be switched between bright and dark states along with the change from the crystalline state to amorphous phase by heating-cooling process. Notably, functionalization over triphenylamine moiety with carboxyl-benzoylhydrazone group in Bodipy-TPA-BH-COOH (3) renders this compound a good solid-state fluorescent sensor due to its fast fluorescence ON-OFF response for HCl vapor in thin film.

    ABSTRACT: A polyoxometalate-based coordination polymer with a [helix + interpenetration] double configuration feature, Na[Ag4(pyttz-I)2][H2PMo12O40] (POMCP-1), was isolated and structurally characterized. POMCP-1 exhibits a 3D structure with open 3D tunnels along the [10−1], [111] and [1−11] axes. The large void space in the single net induces the interpenetration of two identical 3D frameworks, resulting in the formation of a highly ordered two-fold interpenetrating aggregate. To the best of our knowledge, this represents the first example of two-fold interpenetrating POMCPs with helical channels. In particular, POMCP-1 was found to display efficient catalytic activities for the esterification reaction and the photodecomposition of Rhodamine-B.

    ABSTRACT: The role of O2 within the synthesis of phthalocyanines (Pcs) has remained unclear in the past century. Here, we demonstrate that O2 , in cooperation with the solvent n-pentanol, participates in the cyclic tetramerization of phthalonitriles over the half-sandwich complex template [Lu(Pc)(acac)] (acac=acetylacetonate) and terminates the reaction at the stage of uncyclized isoindole oligomeric derivatives rather than the phthalocyanine chromophores, resulting in the isolation of the heteroleptic (phthalocyaninato)(triisoindole-1-one) lutetium double-decker complexes [(Pc)Lu(TIO-I)] (TIO-I=3,4,7,8,11,12-sexi(2,6-diisopropylphenoxy)-15-[4,5-di(2,6-diisopropylphenoxy)-2-cyanobenzimidamido]triisoindole-1-one) and [(Pc)Lu(TIO-II)] (TIO-II=3,4,7,8,11,12-sexi(2,6-dimethylphenoxy)-15-[4,5-di(2,6-dimethylphenoxy)-2-cyanobenzimidamido]triisoindole-1-one) with the help of bulky substituents at the phthalonitrile periphery and an unsubstituted phthalocyanine ligand in the double-decker skeleton. Nevertheless, the cyclic tetramerization of the phthalonitriles was revealed to be sensitive to O2 with the reaction progression also depending on the oxygen concentration/content, leading to the O2 -senstive and -dependent nature for the isolation of phthalocyanine derivatives.

    ABSTRACT: A three-dimensional porous Zn metal-organic framework (UPC-12) with high thermal and chemical stability was isolated in high yield and purity from a hydrothermal reaction. UPC-12 exhibits high selectivity for CO2 due to the formation of hydrogen bonds between CO2 molecules and the -COOH groups exposed inside the channels and the effective π-π interactions between CO2 molecules and the pillared bipyridine moieties of the MOF. The adsorption-desorption process was studied, for the first time, by both (13)C CP-TOSS NMR spectroscopy and in situ DRIFTS.

    ABSTRACT: Unprecedented 2,3,9,10,16,17,23,24-octakis(di-butylamino)phthalocyanine compounds M{Pc[N(C4H9)2]8} (M = 2H, Mg, Cu, Zn) (1-4) were prepared and structurally characterized on the basis of single-crystal X-ray diffraction analysis, representing the first structurally characterized alkylamino-substituted phthalocyanine examples. These novel phthalocyanine derivatives have also been characterized by a wide range of spectroscopic methods including MALDI-TOF mass spectra, NMR, electronic absorption, and IR spectroscopy in addition to elemental analysis. Their electrochemistry was also studied by cyclic voltammetry.

    ABSTRACT: To fully achieve potential applications of the double-decker molecules containing rare earth elements as single-molecule magnets in molecular spintronics, it is crucial to understand the 4f states of the rare earth atoms sandwiched in the double-decker molecules by metal electrodes. In this study, low-temperature scanning tunneling microscopy and spectroscopy were employed to investigate the isolated double-decker DyPc2 molecule adsorbed on Au(111) via its differential conductance measurements. The experimental results revealed that the differential conductance maps acquired at a constant height mode simply depicted the authentic molecular orbitals; moreover, the differential conductance maps achieved at a constant current mode could not directly probe the 4f states of the sandwiched Dy atom. This was consistent with the spectra obtained over the molecule center around the Fermi level, indicative of no Kondo feature. Upon decreasing the tip-molecule distance, the CH-mode images presented high-resolution structure but no information of the 4f states. All results indicated that the Dy atom barely contributed to the tunneling current because of the absence of coupling with the microscope tip, echoing the inaccessibility of the Dy 4f states in the double-decker DyPc2 molecule.

    ABSTRACT: With the coordination geometry of DyIII being relatively fixed, oxygen and sulfur atoms were used to replace one porphyrin pyrrole nitrogen atom of sandwich complex [(Bu)4N][DyIII(Pc)(TBPP)] [Pc = dianion of phthalocyanine, TBPP = 5,10,15,20-tetrakis[(4-tert-butyl)phenyl]porphyrin]. The energy barrier of the compounds was enhanced three times, with the order of DyIII(Pc)(STBPP) > DyIII(Pc)(OTBPP) > [(Bu)4N][DyIII(Pc)(TBPP)] [STBPP = monoanion of 5,10,15,20-(4-tert-butyl)phenyl-21-thiaporphyrin, OTBPP = monoanion of 5,10,15,20-(4-tert-butyl)phenyl-21-oxaporphyrin]. Theoretical calculations offer reasonable explanations of such a significant enhancement. The energy barrier of 194 K for DyIII(Pc)(STBPP) represents the highest one among all the bis(tetrapyrrole) dysprosium SMMs, providing a strategy to rationally enhance the anisotropy and energy barrier via atom replacement.

    ABSTRACT: The hydrophobility of most porphyrin and porphyrin derivates has limited their applications in medicine and biology. Herein, we developed a novel and general strategy for the design of porphyrin nanospheres with good biocompatibility and water dispersibility for biological applications using hydrophobic porphyrins. In order to display the generality of the method, we used two hydrophobic porphyrin isomers as starting material which have different structures confirmed by X-ray technique. The porphyrin nanospheres were fabricated through two main steps. Firstly, the uniform porphyrin nanospheres stabilized by surfactant were prepared by interfacially driven microemulsion method, and then the layer-by-layer method was used for the synthesis of polyelectrolyte-coated porphyrin nanospheres to reduce the toxicity of the surfactant as well as improve the biocompatibility of the nanospheres. The newly fabricated porphyrin nanospheres were characterized by TEM techniques, the electronic absorption spectra, photoluminescence emission spectra, dynamic light scattering and cytotoxicity examination. The resulting nanospheres demonstrated good biocompatibility, excellent water dispersibility and low toxicity. In order to show their application in biophotonics, these porphyrin nanospheres were successfully applied in targeted living cancer cell imaging. The results showed an effective method had been explored to prepare water dispersible and highly stable porphyrin nanomaterial for biophotonics applications using hydrophobic porphyrin. The approach we reported shows obvious flexibility because the surfactants and polyelectrolytes can be optionally selected in accordance with the characteristics of the hydrophobic material. This strategy will expand the applications of hydrophobic porphyrins owning excellent properties in medicine and biology.

    ABSTRACT: A sandwich-type dimer (µ-oxo)bis[tetrakis(p-bromophenyl-porphyrinato) iron(III)] [(TBPP)Fe]2O was prepared under solvothermal condition and structurally characterized for the first time. Its self-assembly behavior has been comparatively investigated with the monomer [(TBPP)Fe]Cl by electronic absorption spectroscopy, scanning electron microscopy (SEM), and powder X-ray diffraction (PXRD) with the help of available single crystal analysis. The optical properties of both compounds were studied by an open aperture Z-scan technique, revealing their good third-order nonlinear optical (NLO) properties. In particular, the µ-oxo dimer shows the about one order of magnitude larger two-photon absorption (TPA) cross-section (σ) value than the monomer due to its more extended conjugated electronic structure.

    ABSTRACT: A novel supramolecular polymer DMeP5@TImPor was successfully constructed between the host molecule bis-(methoxy-pillar[5]arene) (DMeP5) and guest molecule 5,10,15,20-tetrakis{butoxy-4-(1H-imidazol-1-yl)}porphyrine (TImPor) depending on the host-guest interactions and characterized by the combination of various techniques including NMR, DLS, SEM, TEM, and AFM. Addition of competitive guest adiponitrile (ADN) led to effective dissociation of the complex DMeP5@TImPor and re-formation of original guest species, giving additional support for the host-guest interaction-based supramolecular polymer nature of the present system. Interestingly, exposure of this supramolecular polymer thin film to the acidic gas led to the complete quenching of the fluorescence, endowing the system with an application potential in acidic gas detecting.

    ABSTRACT: Novel porphyrin-pillar[5]arene host compound ZnPor-P5 was designed and prepared for the first time. A 1:1 supramolecular complex (ZnPor-P5)•C4 was formed with neutral guest 1,4-bis(imidazol-1-yl)butane (C4) depending on the cooperative interactions between the coordination of zinc ion locating at the center of porphyrin moiety and the inclusion complexation of the pillar[5]arene cavity with the guest molecule according to a range of NMR, mass, electronic absorption, and fluorescence spectroscopic results in addition to ITC, demonstrating the ditopic receptor nature of this porphyrin-pillar[5]arene hybrid compound. Addition of CdI2 into (ZnPor-P5)•C4 in chloroform induced the dissociation of the guest molecule from the zinc ion locating at the center of porphyrin moiety due to the stronger coordination of imidazole with Cd2+ than with zinc ion, yielding a new supramolecular system ZnPor-(P5)•C4•Cd with different conformation.

    ABSTRACT: Fluorescent [2]rotaxane BC12P5 is successfully constructed with 1,4-diethoxypillar[5]arene as wheel over a long alkyl axle with Bodipy chromophore as one stopper for the first time. NMR spectra clearly reveal its molecular shuttle nature triggered by multiple external stimuli including solvent polarity and temperature. In particular, the fluorescence nature introduced into [2]rotaxane BC12P5 renders it a good sensor for the external stimuli. Nevertheless, the supramolecular gel successfully fabricated from this novel rotaxane system via self-assembly in dimethyl sulfoxide (DMSO) also shows reversible gel–sol phase transition upon multiple external stimuli such as heating/cooling, shaking/resting, or the addition of different anions. Interestingly, exposure of the supramolecular gel film to HCl or ammonia vapor induces the change in the film fluorescence intensity, endowing this system with a potential application in gas detecting.

    ABSTRACT: Metal free 5,10,15,20-tetra(p-amino-phenyl)porphyrin (H2TAPP) with additional nitrogen atoms at the tetrapyrrole periphery was employed to construct a nitrogen-rich covalent organic framework (H2P-Bph-COF) with the help of 4,4'-biphenyldialdehyde under solvothermal condition. The abundant and periodically distributed N atoms in H2P-Bph-COF stabilize and uniformly disperse the Pd ions inside the COF structure, resulting in a remarkable catalytic activity towards the Suzuki-coupling reaction between bromoarenes and arylboronic acids under mild condition with high yield of 97.1-98.5%. The present result appears to extend the catalysis application of porphyrin-based COFs from radical or carbene participated oxidation reactions into the Suzuki-coupling reaction.

    ABSTRACT: The periodic octupolar vibrational nature of the electron cloud in sandwich-type bis(phthalocyaninato) yttrium double-decker compounds has been revealed on the basis of coupled perturbed density functional theory. This in turn results in an intense hyper-Rayleigh scattering response and renders the double-decker skeletons excellent second-order hyperpolarizability with a maximum value as high as 5.55×10(6) au (≈10(5) ×10(-30) esu, theoretical prediction) achieved for the molecular conformation with a rotation angle between two phthalocyanine chromophores of approximately 70°. © 2015 WILEY-VCH Verlag GmbH & Co.

    ABSTRACT: A novel chiral ABBB-type unsymmetrical mono(dinaphtho[1,2-e:1',2'-g]-1,4-dioxocine)-[2,3-b]phthalocyaninato zinc complex Zn[Pc(AB3)] was synthesized via a subphthalocyanine ring-expansion reaction with the addition of an activated chiral binaphthyl-linked phthalonitrile. The resulting pair of phthalocyanine enantiomers has been fully characterized by a series of spectroscopic methods including electronic absorption, CD, MCD, fluorescence, and IR spectroscopy in addition to electrochemistry. The CD measurement with explicit signals over the entire region provides a direct image to the chirality induction from the optically active binaphthyl group to the phthalocyanine chromophore.

    ABSTRACT: Three sandwich-type neutral unprotonated mixed (phthalocyaninato)(porphyrinato) dysprosium(III) double-decker complexes Dy(Pc)(Por) [Por = TCPP, TPP, TBPP; Pc = unsubstituted phthalocyaninate, TCPP = 5,10,15,20-tetrakis(4-cyanophenyl) porphyrinate, TPP = 5,10,15,20-tetrakis(phenyl) porphyrinate, TBPP = 5,10,15,20-tetrakis[(4-tert-butyl)phenyl] porphyrinate] (1-3) have been designed, prepared, and structurally studied. Systematic and comparative studies reveal the slow relaxation of magnetization under both zero and applied dc field for all the three double-deckers, indicating their SMM nature. Stronger quantum tunneling of magnetization (QTM) observed for 3 in comparison with its two counterparts 1 and 2 with similar coordination geometry shows the influence of substituent at the meso-attached phenyl moieties on the magnetic properties.

    ABSTRACT: Two pairs of cyanide-bridged Fe(III)-Mn(III)/Cu(II) chiral enantiomer coordination polymers {[Mn(S,S/R,R-Salcy)(CH3OH)2]{[Mn(S,S/R,R-Salcy)][Fe(bbp)(CN)3]}}2n (1,2) (bbp = bis(2-benzimidazolyl)pyridine dianion) and {[Cu(S,S/R,R-Chxn)2]2[Fe2(tbbp)(CN)6]}n (3,4) (tbbp = tetra(3-benzimidazolyl)-4,4’-bipyridine tetraanion) have been successfully prepared by employing mer-tricyanometallate [PPh4]2[Fe(bbp)(CN)3] or the newly bimetallic mer-cyanideiron(III) precursor K4[Fe2(tbbp)(CN)6] as building block and with chiral manganese(III)/copper(II) compounds as assemble segments. The four complexes have been characterized by elemental analysis, IR spectroscopy, circular dichroism (CD) and magnetic circular dichroism (MCD) spectrum. Single X-ray diffraction reveals complexes 1 and 2 possess single anionic chain structure consisting of the asymmetric chiral {[Mn(S,S/R,R-Salcy)][Fe(bbp)(CN)3]}22- unit with free [Mn(S,S/R,R-Salcy)]+ as balanced cations. The cyanide-bridged Fe(III)-Cu(II) complexes 3 and 4 can be structurally characterized as neutral ladder-like double chain composed by the alternating cyanide-bridged Fe-Cu units. Investigation over magnetic susceptibilities reveals the antiferromagnetic coupling between the cyanide-bridged Fe(III) and Mn(III)/Cu(II) ions for complexes 1-4. These results have been further confirmed by theoretical simulation through numerical matrix diagonalization techniques by using a Fortran program or an uniform chain model, leading to the coupling constants J= -7.36 cm-1, D =-1.52 cm-1 (1) and J = -4.35 cm-1 (3), respectively.

    ABSTRACT: Organic thin film transistor (OTFT) devices fabricated by the solution-based QLS technique from a mixed (phthalocyaninato)(porphyrinato) europium complex (TFPP)Eu[Pc(OPh)8]Eu[Pc(OPh)8] exhibit air-stable ambipolar performance with mobilities of 6.0 × 10-5 for holes and 1.4 × 10-4 cm2 V-1 s-1 for electrons, respectively. In good contrast, the two-component bilayer heterojunction thin film devices constructed by directly growing (TFPP)Eu[Pc(OPh)8]Eu[Pc(OPh)8] on vacuum deposited (VCD) CuPc film using solution based QLS method were revealed to show unprecedented ambipolar performance with carrier mobilities of 0.16 cm2 V-1 s-1 for holes and 0.30 cm2 V-1 s-1 for electrons. In addition to the intrinsic role of p-type organic semiconductor, the VCD CuPc film on the substrate also acts as a good template that induces significant improvement over the molecular ordering of triple-decker compound in the film. In particular, it results in the change in the aggregation mode of (TFPP)Eu[Pc(OPh)8]Eu[Pc(OPh)8] from J-type in the single-layer film to H-type in the bilayer film according to the UV-vis, XRD and AFM observations.
