Lead-halides Perovskite Visible Light Photoredox Catalysts for Organic Synthesis.

Lead-halide perovskites has grabbed great attention in recent years due to its unique photophysical and electrical properties. It has open new window in organic solar cell application for commercial point. Research has extended its application further towards visible light photoredox catalysts for organic synthesis. Due to intrinsic redox properties, sharp absorption and emissions patterns makes lead-halide perovskites as promising photoredox catalyst. In the presence of light, perovskite absorbs light, generates electrons/holes, which can reduce or oxidize species at reactive centres of organic molecule, leads to organic transformation. Lead-halide perovskites are used as heterogeneous catalysts for small molecules activations like CO, CH4 and NO, also suitable photocatalysts for organic bond formations, oxidations, reductions, polymerizations and dimerization transformations. Recent literatures have set another milestone for perovskite materials in organic synthesis. This review provides information on lead-halides perovskite in visible-light photoredox catalysis such as C-C, C-X (X-halo, hetero atom) bond formations C-H arylation.
