“…Hydrogenation of substituted nitroarenes follows a complicated reaction mechanism with multiple elementary steps and various final products, depending on the catalyst types and reaction conditions [44][45][46]. Typical products for Pt-catalyzed 3-NS hydrogenation [3,4] are shown in a simplified reaction scheme (Fig.…”

Sensitization of heavy metal free organic dyes onto TiO 2 thin films has gained much attention in dye sensitized solar cells (DSSCs). A series of new kojic acid based organic dyes KA -were synthesized via nucleophilic substitution of azobenzene bearing different vinyl chains A -with kojyl chloride . Azo dyes KA -were characterized for photophysical properties employing absorption spectrometry and photovoltaic characteristic in TiO 2 thin film. The presence of vinyl chain in A -improved the photovoltaic performance from 0.20 to 0.60%. The introduction of kojic acid obtained from sago waste further increases the efficiency to 0.82-1.54%. Based on photovoltaic performance, KA achieved the highest solar to electrical energy conversion efficiency ( = 1.54%) in the series.

“…Finally, azobenzenes are relatively easy to synthesize and modify, as several synthetic strategies are available, including diazonium coupling, Mills reactions, and transition-metal-catalyzed cross-coupling strategies. [40] One potential disadvantage is their comparatively low solubility, but this can usually be overcome with appropriate functional groups, in particular with charged substituents.…”

Transmembrane receptors allow a cell to communicate with its environment in response to a variety of input signals. These can be changes in the concentration of ligands (e.g. hormones or neurotransmitters), temperature, pressure (e.g. acoustic waves or touch), transmembrane potential, or light intensity. Many important receptors have now been characterized in atomic detail and our understanding of their functional properties has markedly increased in recent years. As a consequence, these sophisticated molecular machines can be reprogrammed to respond to unnatural input signals. In this Review, we show how voltage-gated and ligand-gated ion channels can be endowed with synthetic photoswitches, and how the resulting artificial photoreceptors can be used to optically control neurons with exceptional temporal and spatial precision. They work well in animals and might find applications in the restoration of vision and the optical control of other sensations. The combination of synthetic photoswitches and receptor proteins contributes to the field of optogenetics and adds a new functional dimension to chemical genetics. As such, we propose to call it "optochemical genetics".
