Visible-light irradiation (λ < 600 nm) of commercially-available CdS in alcohol successfully promotes hydrogenation of azobenzene to hydrazobenzene with more than 95% selectivity. This is promoted by strong adsorption of azobenzene to the photoformed zerovalent Cd species adjacent to the surface S vacancies on CdS; this leads to efficient reduction to hydrazobenzene.

Photoexcitation (λ > 300 nm) of TiO2 loaded with Pt nanoparticles promotes selective hydrogenolysis of epoxides using alcohols as reducing agents.

TiO(2) loading Pt nanoparticles (Pt@TiO(2)) promote one-pot synthesis of imines from alcohols and amines under UV irradiation at room temperature. This is achieved via a Pt-assisted photocatalytic oxidation of alcohols and a catalytic condensation of the formed aldehydes with amines on the TiO(2) surface.

A resorufin–dinitrophenyl ether conjugate (1) shows emission enhancement for aromatic thiols in aqueous media with a neutral–basic pH, while being nonemissive for aliphatic thiols. This is achieved by two electrophilic sites with different local softness on compound 1; the respective sites selectively react with aromatic or aliphatic thiolate anions.

A spiropyran-amide-dipicolylamine linkage behaves as a colorimetric receptor for selective Co(2+) sensing in aqueous media under UV irradiation. This is promoted by strong coordination of Co(2+) with amide oxygens of the receptors and efficient photoisomerization of the spiropyran moieties.

A boradiazaindacene (BODIPY) derivative containing a simple NO bidentate ligand shows a Cu(2+)-selective fluorescence in aqueous media. This is promoted via a coordination of Cu(2+) followed by oxidative dehydrogenation of an amine moiety, leading to a formation of a fluorescent Cu(+)-Schiff base complex.

A novel desulfurization process for light oil, based on N-tosylsulfimide formation by the reaction of sulfur compounds with chloramine T (sodium N-chlorotoluene-p-sulfonamide), has enabled deep desulfurization at ambient temperature.

A polymeric photosensitizer, poly(NIPAM-co-RB), consisting of N-isopropylacrylamide and rose bengal units, demonstrates a temperature-controlled changeable oxygenation selectivity by singlet oxygen in water.

A visible light-induced desulfurization process for light oil, effected by electron-transfer photooxygenation and liquid–liquid extraction, allows the deep desulfurization of light oil under moderate conditions and without hydrogen.

Cr-Si binary oxide prepared by a sol-gel method, when activated by visible light, catalyses highly selective oxidation of cyclohexane to cyclohexanone with molecular oxygen.

Simple polyamines, L1-L3, bearing anthracene and benzophenone units at the respective ends, behave as a fluorescent pH sensor applicable to wide-range pH detection.

A simple molecule, L, diethylenetriamine bearing anthracene fragments at both ends, behaves as a fluorescent molecular logic gate with "multiply-configurable dual outputs", capable of demonstrating five different logic functions operated by proton (H+) and transition metal cations (Mn+) as inputs.

Highly selective photocatalytic epoxidation of olefins proceeds on Ti-containing silica with tetrahedrally coordinated Ti-oxide species with molecular oxygen and a simple addition of MeCN.
