and light. Direct capture of solar energy for organic synthesis is a promising approach. Lead (Pb)-halide perovskite solar cells reach 24.2% power conversion efficiency, rendering perovskite a unique type material for solar energy capture. We show that photophysical properties of perovskites is useful in photoredox organic synthesis. Because the key aspects of these two applications are both relying on charge separation and transfer. Here we demonstrated that perovskites nanocrystals are exceptional candidates as photocatalysts for fundamental organic reactions, i.e. C—C, C—N and C—O bond-formations. Stability of CsPbBr

readily prepared anthrazoline photocatalyst, which can effectively promote C—O bond formation reactions with the aid of Ni(II) complex. This methodology enables the esterification (36 examples) and etherification (8 examples) with a broad range of scope, allowing aryl and alkyl halides coupled with diverse carboxylic acids/alcohols. Our metal-free photocatalysts have a potential broad application, may
