    ABSTRACT: This work focuses on different ways to improve the yield and/or the crystalline state of EMT/FAU-type zeolite nanocrystal aggregates obtained in the presence of organic additive triethanolamine (TEA). The increase of the amount of aluminum reagent enhances the synthesis yield by a factor of 2.5 without affecting the crystallization rate and the microporous volume. On the other hand, the increase of the thermal treatment time allows to increase the synthesis yield, the crystallization rate and the microporous volume. Furthermore, adding EMT zeolite seeds in the starting reaction medium improves the crystallization rate and the microporous volume.

    ABSTRACT: The structural, electro-optical and charge-transport properties of compound trans-3-(3,4-dimethoxyphenyl)-2-(4-nitrophenyl)prop-2-enenitrile (DMNPN) were studied using quantum chemical methods. The neutral, cation and anion molecular geometries were optimized in the ground state using density functional theory (DFT) at the restricted and unrestricted B3LYP/6-31G** level of theory. The excited state geometries were optimized by applying time-dependent DFT at the TD-B3LYP/6-31G** level of theory. The absorption and fluorescence wavelengths were calculated at the TD-CAM-B3LYP/6-31G** and TD-LC-BLYP/6-31G** levels of theory. The distribution pattern of the charge densities on the highest occupied molecular orbitals (HOMOs) and lowest unoccupied molecular orbitals (LUMOs) are discussed. Intramolecular charge transfer was observed from the dimethoxyphenyl to (nitrophenyl)prop-2-enenitrile moieties. The detailed charge-transport behavior of the DMNPN molecule is investigated based on its ionization potential, electron affinity, hole and electron reorganization energies, hole and electron-transfer integrals, and hole and electron intrinsic mobilities. The total/partial densities of states and structure–property relationship are discussed in detail. The higher computed hole intrinsic mobility than electron intrinsic mobility reveals that DMNPN is an efficient hole-transport material.

    ABSTRACT: A theoretical study was performed on the [3+2] cycloaddition (32CA) reaction between benzonitrile sulfide BNS1 and trichloroacetonitrile TCAN2 at the MPWB1K/6-311G(d) level. Among two feasible C1-N5 and C1-C4 regioisomeric channels, in the presence of toluene, the former is completely preferred over the latter both kinetically, ∆∆Gactivation= 17.5 kcal/mol, and thermodynamically, ∆∆Greaction= -12.8 kcal/mol, in excellent agreement with experimental outcomes. The strong global electrophilic and nucleophilic characters found for TCAN2 and BNS1, respectively, allow the studied 32CA reaction take place via a polar process. Interestingly, analysis of TSs geometries clarifies that in the case under study regioselectivity is controlled by destabilizing steric repulsion interactions rather than the electronic ones. The ELF topological patterns indicate that while the formation of S3-C4 single bond takes place exactly according to the Domingo’s model, formation of C1-N5 single bond is a direct consequence of nucleophilic attack of C5 carbon atom on the N5 nitrogen atom supporting a two-stage one-step molecular mechanism.

    ABSTRACT: A simple biomolecule-inspired chemical procedure was adopted for the successful synthesis of cadmium sulphide nanoparticles (CdS-G and CdS-M) using glucose and maltose as capping agents. These nanoparticles were characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Energy dispersive X-ray (EDAX) and Ultraviolet-Visible (UV–Vis) spectroscopy in order to evaluate their particle size, morphology, and optical properties. The photocatalytic degradation of methylene blue (MB) by CdS-G and CdS-M nanoparticles under visible light was estimated and the kinetics of photocatalytic degradation were compared by the evaluation of operational parameters viz., an amount of the photocatalyst, the pH of the solution, and concentration of the dye. The mechanism of generation of hydroxyl radicals on the surface of the CdS-G/M nanoparticles upon visible-light irradiation was confirmed by the terephthalic acid photoluminescence technique. The study of the effect of tert-butyl alcohol (TBA) and of a disodium salt of ethlyenediamine tetraacetic acid (EDTA-2Na) as scavengers, as well as photoluminescence measurements, revealed that HO• and hole (h+) were the reactive species responsible for the degradation of MB. The anthelmintic activity of CdS-G/M nanoparticles was also evaluated.

    ABSTRACT: The purpose of this review is to analyze the different reaction mechanisms of the H/D exchange on organic substrates catalyzed by transition metal complexes in homogeneous phase. The metal-catalyzed H/D exchange is a multifaceted reaction whose mechanism depends strongly on the reaction conditions and on the metal complex used as a catalyst. It is possible to group the different mechanisms into three main families depending on the “role” and behavior of the catalyst: (i) Lewis acid–base catalysis; (ii) CH activation (iii) insertion/β-elimination. For each macro-group, several representative examples are discussed and critically evaluated in order to provide the reader with keys to the understanding of how the different catalytic systems act and how their modification may affect their performance in terms of activity and selectivity. This knowledge is fundamental for designing improved organometallic H/D catalysts for labeling organic products in greener conditions with more cost-effective processes.

    ABSTRACT: A series of mononuclear Cu(I)–halide complexes, [CuX(PPh3)2(L)] (X = Cl−, Br−, I−; PPh3 = triphenylphosphine; L = pyridine (py), isoquinoline (iq), 1,6-naphthyridine (nap)), were synthesized. The emission color of [CuX(PPh3)2(L)] varies from blue to red by changing the L ligands and the halide ions, and all the complexes exhibit high emission quantum yields (0.16–0.99) in the crystals. The emission studies revealed that the emissive states of [CuX(PPh3)2(L)] differ depending on the L ligand. Complexes [CuX(PPh3)2(py)] and [CuX(PPh3)2(nap)] mainly emit from the singlet metal-to-ligand charge transfer mixed with the halide-to-ligand charge transfer (1(M + X)LCT) state at room temperature. In contrast, emissions from [CuX(PPh3)2(iq)] at room temperature originate from both 3(M + X)LCT and 3ππ* states. These results indicate that N-heteroaromatic ligands play an important role in the emission properties of mononuclear Cu(I)–halide complexes.

    ABSTRACT: We defined the smallest enclosing cone angle as the Tolman cone angle for null atomic spheres radii. Then we provide a simple analytical algorithm to compute the smallest enclosing cone at fixed apex, which works in the case of unsymmetrical ligand. We applied it to compute ligand cones for a family of triphenylphosphine palladium complexes, and we showed that both the angle of the cone and its resulting solid angle strongly correlate with the Tolman cone angle, thus suggesting that there is no more need for atomic radii. We also defined the best cone of fixed apex fitting a population of unit vectors. We proposed a simple analytical algorithm to compute it, which is proved to work in any d-dimensional Euclidean space. We defined the conicity index κ to evaluate quantitavely the pertinence of the best fitting cone. We used this best fit cone to define a mean ligand cone, and thus a mean cone angle and a mean cone axis. We applied it to our family of triphenylphosphine palladium complexes and we observed that the axis of the individual cones deviated from the mean cone axis by at most 13.2°. The observed conicity index was small , indicating a very good fit for the whole family of complexes.

    ABSTRACT: A novel protonated polymeric tpphz ligand along with as a counterion, {[H2tpphz][CoCl4]}n (where tpphz = tetrapyrido[3,2-a:2’,3’-c:3”,2”-h:2”’,3”’-j] phenazine), has been synthesized and characterized by elemental analysis, Fourier transform infrared spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), and single-crystal X-ray diffraction analysis. The compound crystallizes in the monoclinic system with space group C 1 2/c 1 (No. 15). The crystal structure showed a layered structure based on an uncoordinated cobalt ion, and the planar heterocyclic H2tpphz2+ ion and different types of hydrogen bonds together with π···π and C–H···π stacking are dominant. The experimental studies on the compounds have been accompanied computationally by Density Functional Theory (DFT) calculations.
