Hole transport materials (HTMs) assisted halide perovskite solar cells (PSCs) revealed excellent performance in photovoltaic technology within a short time period. Herein, a cost-effective hole transport materials (HTMs) namely BTBDT...

The Schiff's base metal complexes have been concerned significantly due to their out-of-box applications in the environmental quantum leap by mineralization of the organic pollutants to fewer harmful byproducts and oxygen generation such as photosynthesis process. The Ti 4+ complexes obtained from Schiff base ligands reacted with donor atoms such as S and N under solvothermal conditions. These complexes were characterized using the microanalysis, conductivity studies, and different spectral techniques. From these data reveals that the compound shows distorted octahedral geometry with ligands coordination via azomethine nitrogen and thiol sulfur atoms. Oxidation of allylic methyl group examined the photocatalytic activity of [Ti(L)O] under ambient conditions and oxidative and cyclization under visible light irradiation. Ti(DCMPPT)O complex is very efficient catalyst due to the very short span of time convert aldehydes from allylic compounds. Aldehydes ready to react with 2-aminophenol or 2-aminobenzenethiol to produce (E)-2-styrylbenzo[d]oxazoles and (E)-2-styrylbenzo[d]thiazoles. Due to the suitable of the bandgap energy of nature to the generation of • OH radicals during the catalytic reaction. For this reason, higher oxidation rate. [Ti(DCMPPT)O] as a very efficient photocatalyst for degradation of MB, due large surface area and that supports to lower recombination energy mechanism.
