    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: Photoinduced charge transfer (CT) is a fundamental process that determines the overall energy conversion efficiency of organic solar photovoltaic cells (OPVs). This review focuses on the advantages and pitfalls of theoretical/computational methods available to describe CT excitations in donor–acceptor (D–A) complexes. Studies of porphyrin–fullerene constructs as model D–A systems will be used to illustrate progress in this area.

    ABSTRACT: As an analogue of graphite, graphitic carbon nitride (g-C3N4) has been the hotspot in the materials science for its unique electronic structure. With medium band gap as well as thermal and chemical stability in ambient environment, it becomes one of the most promising photocatalytic materials. Intensive investigation has been focus on its photocatalytic performance for various reactions to date. What is more, controllable modulation of its electronic structure via doping or chemical functionalization is available. In addition, considerable attention has been paid on its photoelectronic application, such as light emitting device, photocathode, optical sensor etc. Based on the electronic properties and pathway to modulate its electronic structure, in this review, we highlight the applications of g-C3N4 ranging from photocatalytic to photoelectronic materials.

    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.

    ABSTRACT: The modification of photocatalysts by silver addition or deposition can be used to increase photocatalytic efficiencies by preventing photogenerated electron-hole recombination through an electron trapping mechanism, and by increasing the visible light absorption of the composite material through the surface plasmon resonance enhancement of silver nanoparticles. Nanosilver also possesses excellent antimicrobial activity, and can be used as a biocidal agent when incorporated into TiO2 photocatalysts. Alternatively, the host photocatalyst may also contribute to the antimicrobial activity observed in the absence of irradiation, such as for AgX (X = Cl, Br, I) and ZnO. These silver-modified composites present a novel class of hybrid nanomaterials, which possess antibacterial and/or antiviral action in both dark and light conditions, and are discussed in detail in this review. In addition, other antimicrobial photocatalysts such as those based on copper are examined. Further work should be performed on distinguishing the roles of the acting mechanisms in the light-induced disinfection processes.

    ABSTRACT: Graphene materials have recently attracted considerable attention because of its extraordinary mechanical, electronic, thermal and optical properties, leading to the wide application of graphene such as in biology and energy areas. In recent years, energy-transfer based optical biosensors using graphene materials as the energy acceptors have become the focus of researches, which take the advantages of the high surface area and ultrahigh luminescence quenching efficiency of graphene materials. These sensors have extensively covered the detection of DNA, protein, enzyme activity, metal ions and other small molecules. In this review article, we aim to provide a comprehensive discussion on the development of the graphene materials-based energy acceptor systems and sensors, sorting the sensors according to the probes with which the energy acceptors are assembled to or conjugated with the luminescent energy donors. At the end we also present an overview of future perspective and possible challenges in this rapidly developing area.

    ABSTRACT: Acenes are highly promising p-type organic semiconductors, and have been the subject of intense studies. However, acenes are often low in solubility and stability, which poses major obstacles in the synthesis and processing of this class of compounds. In order to overcome the problem, a series of α-diketone-type acene precursors have been developed. These precursors are generally more soluble and stable than the corresponding acene compounds, and their quantitative conversion can be achieved simply by photoirradiation both in solution and in the solid state. Further, the irreversible photoinduced removal of the α-diketone unit can be used to alter the optoelectronic properties of fluorophores. This review overviews the synthesis and photochemical properties of α-diketone-type acene precursors, as well as their use as intermediates in preparation of large acenes or highly functionalized acene derivatives. Computational studies on the mechanism of α-diketone photolysis and the use of α-diketone derivatives in fabrication of organic devices are also summarized in this review.

    ABSTRACT: Photobiological production of hydrogen is considered to be one of the most promising technologies for replacing or complementing fossil fuel-derived energy. This review focuses on the bioenergetics of photobiological hydrogen production by various phototrophs, namely purple non-sulfur bacteria, green sulfur bacteria, cyanobacteria, and green algae. We discuss the improvements in hydrogen production efficiency and the advances in related technologies that are needed before phototrophs can be used for economically-viable hydrogen production. We also discuss some technological aspects such as the cost of nutrients and bioreactors, which should be taken into consideration in designing future plans for the application of photobiological hydrogen production.

    ABSTRACT: Femtosecond laser ablation in solution (FLAS) is a unique and simple technique addressing the drawbacks of the conventional methods giving access to preparation of an ultra-broad spectrum of nanomaterials (NMs), since the NMs can be produced from nearly any solid materials and variable precursors in different solutions. After the energy injection in ultra-short time, extreme conditions with high temperature, high pressure and high cooling rate are created, under which many interesting phenomena occur, including nanomaterial formation. Characteristic advantages of this method are the applications in preparing a huge variety of NMs, the high purity of the products, and the in situ dispersion and functionalization of the as-prepared NMs in various solutions. This review is devoted to give a comprehensive understanding of the fundamental mechanisms of FLAS. A map of variable NMs prepared by FLAS and the promising applications are built up to pave the way for more future work in this field.

    ABSTRACT: The one-dimensional π-conjugated structure endows carbon nanotube (CNT) with large specific surface area and excellent photophysical properties, thus providing a unique platform for the development of chemo- and biosensors based on optical signal output. Although CNT acts as an optical signal transducer, it does not own any intrinsic ability for the selective binding and recognition of analytes. Thus, hybridization of CNTs with functional components that specifically recognize various chemical and biomolecular analytes is often necessary in the preparation of CNT-based sensors. In this review, we summarize preparation and photophysical properties of CNT-based composites, and then highlight on fluorescence sensors based on CNT-composites. These composite sensors integrate the signal transduction property of CNT and the recognition properties of the hybridized functional components. The functional components selectively bind with the target analytes, whereas, CNTs transform the binding events into output signals detectable using spectrofluorometer. Particularly, we highlight on recent progress in the chemical and bimolecular sensors based on near-infrared fluorescence of semiconducting single-walled CNT (SWCNT) and the excellent fluorescence quenching ability of CNTs over conventional organic quenchers.

    ABSTRACT: The photoprocesses of water ice play an important role in regions of interstellar space, such as interstellar clouds and outer solar systems. Vacuum-ultraviolet absorption of water ice leads to dissociation of water molecules, and allows subsequent reactions of photoproducts on/in ice. There have been many laboratory studies that identify photoproducts and estimate product yields, reaction mechanisms and energy partitioning in the reaction products. Among them, the experimental approaches aimed at understanding the photoprocesses on the water ice surface can give new insight into the chemical reaction network in interstellar space. In this review, we focus on photochemical processes of water ice relevant to surface astrochemistry following vacuum-ultraviolet photolysis of water ice at a low temperature from a surface reaction dynamics’ point of view.
