    ABSTRACT: We review the results obtained for PtIVCl62−, PtIVBr62−, IrIVCl62−, IrIVBr62−, and OsIVBr62− complexes in aqueous and alcoholic solutions using ultrafast pump-probe spectroscopy, laser flash photolysis, ESR, and photoelectron spectroscopy. We discuss the correlations between the photophysics and the photochemistry of these complexes. The key reaction for PtIVCl62− is the inner-sphere electron transfer, which results in an Adamson radical pair that lives for several picoseconds, and the subsequent photoaquation in aqueous solutions and photoreduction in alcohols. The chlorine atom formed as the primary product escapes the solvent cage in aqueous solutions or oxidizes a solvent alcohol molecule via secondary electron transfer, producing secondary intermediates that react on the microsecond time scale. The photoexcitation of PtIVBr62− results in the formation of pentacoordinated PtIV intermediates, i.e., 3PtIVBr5− and 1PtIVBr5−, with characteristic lifetimes of approximately 1 and 10 ps, respectively. Subsequent reactions of these intermediates result in the complexation of a solvent molecule. Photoreduction is also possible in alcohols. Similar reactions occur with rather low quantum yields for IrIVCl62−, therefore, only the ground-state recovery could be monitored in ultrafast experiments, which occur on the 10-ps time scale. The photochemical behaviours of the IrIVBr62− and OsIVBr62− complexes are similar to those of IrIVCl62− and PtIVBr62−, respectively.

    ABSTRACT: ‘Supramolecular Photochemistry’ (SP) deals with a study of the properties of molecules in their excited states where the medium plays a significant role. While ‘Molecular Photochemistry’ (MP) deals with studies in isotropic solution, the SP deals with reactant molecules that interact weakly with their surroundings. The surroundings in general are highly organized assemblies such as crystals, liquid crystals, micelles, host-guest structures etc. The behavior of exited molecules in SP unlike in isotropic solution is controlled not only by their inherent electronic and steric properties but also by the immediate surroundings. The weak interactions that control the chemistry include van der Walls, hydrophobic, C-H---π, π---π and several types of hydrogen bonds. In this review the uniqueness of SP compared to MP is highlighted with examples chosen from reactions in crystals, micelles and host-guest assemblies. In spite of distinctly different structures (crystals, micelles etc.) the influence of the medium could be understood on the basis of a model developed by G. M. J. Schmidt for photoreactions in crystals. The principles of reaction cavity model are briefly outlined in this review. There are a few important features that are specific to SP. For example, highly reactive molecules and intermediates could be stabilized in a confined environment; they enable phosphorescence to be observed at room temperature and favor chiral induction in photochemical reactions. Using such examples the uniqueness of SP is highlighted. The future of SP depends on developing efficient and unique catalytic photoreactions using easily available reaction ‘containers’. In addition, their value in artificial photosynthesis should be established for SP to occupy a center stage in the future.

    ABSTRACT: Photonic crystals are periodic dielectric nanostructures that can affect the propagation of light. Polymer-based photonic crystals have attracted great attentions for their potential application as sensors or optical switches due to their stimuli-responsive properties. This review summarizes the recent developments in one-dimensional (1-D) polymer-based photonic crystals, including the inspiration of the material from nature, principles for design and fabrication, mechanism of color tuning, and their tunable structural color in responsive to various stimuli. A number of fabrication methods, either by bottom-up or top-down approaches for 1-D polymeric photonic crystals have been overviewed.

    ABSTRACT: Aggregation-Induced Emission (Enhancement) (AIE(E)) is an extraordinary phenomenon in the field of photochemistry and offers a new platform for researchers to investigate the light-emitting process from nanoaggregates. Non- or weakly emissive molecules are induced to emit efficiently through nanoaggregate formation, which are referred to as aggregation-induced emission (AIE) and aggregation-induced emission enhancement (AIEE) respectively. A large number of AIE/AIEE active organic molecules have now been developed and reviews on them appeared. Comparatively little attempt is made on the AIEE activity based on organometallic and coordination complexes. In the case of most of the transition metal complexes intersystem crossing from the excited S1 to T1 state is close to unity and predominant emission process is phosphorescence. This review concentrates on the design, synthesis, and photophysical behavior and important applications of aggregation-induced phosphorescence enhancement (AIPE) -active molecules based on transition metal complexes. Researchers have incorporated a rotating or isomerizable or long alkyl chain unit in the ligand or cyclometalated ligand, to generate a family of AIPE active members. Several transition metal complexes including Re(I), Ir(III), Pt(II), Au(I), Zn(II) and Cu(I) have been demonstrated to exhibit a significant AIPE phenomenon in the presence of appropriate stimuli. The phosphorescence intensity and quantum yield could be enhanced by adding poor solvents to induce nanoaggregate formation to restrict the intramolecular rotation or isomerization. The characteristics of highly phosphorescent aggregates differentiate them from conventional chromophores and make them ideal candidates for high-tech applications in the field of chemosensors, bioprobes, stimuli-responsive nanomaterials and optoelectronic materials, etc.

    ABSTRACT: The development of biologically templated artificial light harvesting antennae and energy transfer devices is a highly active research area with exceptional challenges. Natural energy harvesting complexes have exquisite spectrally- and spatially-tuned systems with high redundancy to maximize their ability to gather, channel, and distribute electromagnetic radiation. Attempting to mimic these highly efficient systems requires at the very least (sub)nanoscale precision in the positioning of light sensitive molecules, the latter of which must also possess carefully selected photophysical properties; in essence, these two fundamental properties must be exploited in a synergistic manner. First, the scaffold must be highly organized, ideally with multiple symmetrical components that are spatially arranged with nanoscale accuracy. Second, the structure must be amenable to chemical modification in order to be (bio)functionalized with the desired light sensitive moieties which have expanded greatly to now include organic dyes, metal chelates, fluorescent proteins, dye-doped and noble metal nanoparticles, photoactive polymers, along with semiconductor quantum dots amongst others. Several families of biological scaffolding molecules offer strong potential to meet these stringent requirements. Recent advances in bionanotechnology have provided the ability to assemble diverse naturally-derived scaffolds along with manipulating their properties and this is allowing us to understand the capabilities and limitations of such artificial light-harvesting antennae and devices. The range of scaffold or template materials that have been used varies from highly symmetrical virus capsids to self-assembled biomaterials including nucleic acids and small peptides as well as a range of hybrid inorganic-biological systems. This review surveys the burgeoning field of artificial light-harvesting and energy transfer complexes that utilize biological scaffolds from the perspective of what each has to offer for optimized energy transfer. We highlight each biological scaffold with prominent examples from the literature and discuss some of the benefits and liabilities of each approach. Cumulatively, the available data suggest that DNA is the most versatile biological material currently available, though it has challenges including precise dye placement and subsequent dye performance. We conclude by providing a perspective on how this field will progress in both the short and long term, with a focus on the transition to applications and devices.

    ABSTRACT: The cryptochrome/photolyase superfamily is a class of flavoproteins that can regulate the growth and development in plants, as well as the circadian clock and the potential magnetic navigation in animals, primarily by absorbing UV-A and blue light. It is generally agreed that these functions depend on the photochemical reaction of the flavin adenine dinucleotide (FAD) chromophore, non-covalently binding to cryptochromes or photolyases. Irradiation can initiate either photoreduction between FAD and certain electron donors or electron jumping in FAD, thereby leading to the generation of intermediates that activate the protein. This signaling process is known as photoactivation. Subsequently, the activated protein will interact with downstream receptors to transfer the photo and magnetic signals. Based on in-depth research on photoactivation, two photo-cycle mechanisms for the photoreception/photosignaling of the cryptochrome/photolyase superfamily, i.e., the photolyase model and the phototropin model, have been proposed. There is no apparent alternative to the photo-cycle of cyclobutane pyrimidine dimer (CPD) or (6-4) photolyase following the photolyase model. However, the mechanism is not clear for the photoactivation of cryptochromes and CRY-DASH, a new subcategory of photolyase. Since the photoactivation process is the first step for the physiological function of proteins, more and improved research efforts in this field have been widely developed. This review first briefly presents the structure, the photoactivation, and the repair mechanism of CPD and (6-4) photolyase. Next, we review in detail the photoactivation of cryptochromes and CRY-DASH by analyzing the current status of research, as well as the contradictions in the resting redox states of FAD, intermediates in photoreactions, the photo-cycle of FAD, the singnaling state of proteins, and the necessity of given tryptophans for protein activity. Based on these studies, the correlations of photoactivation and photo-cycle mechanisms, as well as the correlations of photoactivation and megnetoreception of proteins, are discussed. Finally the crucial open questions regarding the photoactivation mechanisms of the cyrptochrome/photolyase superfamily are outlined, considering the hypothesis for a cryptochrome-based model of avian magnetoreception.

    ABSTRACT: Electron injection processes in dye-sensitized solar cells (DSCs), which involve electron transfer from an excited dye to a semiconductor nanoparticle, have been discussed in many previously reported studies. In this review we discuss the working principles and primary processes of DSCs, as well as these processes' influence on basic properties of solar cells such as open-circuit voltage, short-circuit current, and incident photon-to-current conversion efficiency (IPCE). We focus our attention on the electron injection process, and we introduce methods to determine electron injection efficiency (Phi(inj)) using time-resolved fluorescence and absorption spectroscopy techniques. We present difficulties associated with obtaining Phi(inj) by means of such techniques, and we propose nanosecond time-resolved transient absorption spectroscopy as a reliable method. Then, Phi(inj) values obtained are summarized. Factors limiting Phi(inj) are discussed from the perspective of free energy changes for electron injection, the molecular structure of sensitizer dyes on the surface, and the presence of fast charge recombination pathways.

    ABSTRACT: Although the photophysics and photochemistry of aromatic carbonyl compounds have been extensively studied over several years, the interest in their photobehaviors is still alive and they continue to be investigated by exploiting advanced experimental and computational technologies. In this article complete series of pyridyl, di-pyridyl, thienyl, di-thienyl and thienyl-pyridyl ketones are reviewed, mainly from the spectroscopic and photochemical points of view. Properties and reactivity of their excited states have been investigated through stationary absorption and emission spectra, time resolved transient spectroscopy, dynamic luminescence techniques and computational methods. The results reported demonstrate that the photophysics and photochemistry of these molecules can be modulated by changing the rings linked to the carbonyl (pyridyl, thienyl, phenyl) and their linking position, as also the microenvironment where they are included. Of special importance are their properties of triplet photosensitizers and their ability in photogenerating free radicals. Enhancing or depressing such properties may be required in applications and this can be achieved by structure and environment changes.

    ABSTRACT: Hydrogen generated through the photochemical cleavage of water using renewable solar energy is considered to be an environmentally friendly chemical fuel of the future, which neither results in air pollution nor leads to the emission of greenhouses gases. The photocatalytic materials for water cleavage are required to perform at least two fundamental functions: light harvesting of the maximal possible part of the solar energy spectrum and a catalytic function for efficient water decomposition into oxygen and hydrogen. Photocatalytic systems based on colloidal semiconductor nanocrystals offer a number of advantages in comparison with photoelectrochemical cells based on bulk electrodes: (i) a broad range of material types is available; (ii) higher efficiencies are expected due to short distance charge transport; (iii) large surface areas are beneficial for the catalytic processes; (iv) flexibility in fabrication and design which also allows for tuning of the electronic and optical properties by employing quantum confinement effects. The presence of co-catalysts on colloidal semiconductors is an important part of the overall design of the photocatalytic colloidal systems necessary to maximize the water splitting efficiency. This review article discusses the rational choice of colloidal nanoheterostructured materials based on light-harvesting II-VI semiconductor nanocrystals combined with a variety of metal and/or non-metal co-catalysts, with optimized light harvesting, charge separation, and photocatalytic functions.
