Visible-Light Photocatalysis Using CsPbX3 Perovskite Nanocrystals for Organic

The increasing interest in efficient organic synthesis by applying solar radiation has propelled a surge in the demand for introducing new types of photocatalysts in synthetic toolboxes. During the last few decades, tremendous efforts have been invested in developing low-cost, non-toxic, stable, and potent photocatalysts. In this perspective, Cesium Lead Halide perovskite (CsPbX3) nanocrystal has emerged as a brand new photocatalyst, creating a renaissance in pioneering organic photochemistry with its enchanting optoelectronic features. Due to their unique band structure, tunable bandgap, and near unity quantum yield, these highly fluorescent nanocrystals are exceptional candidates to catalyze numerous fundamental organic transformations by absorbing energy from ultraviolet to visible regions. Also, anion metathesis, long average excited state lifetime, tunable morphology, and photo-generated charge carriers, make them capable of a broader range of organic substrate activation in bench-stable conditions. These nanocrystals are well known for their superb power conversion efficiency (PCE) of solar radiation which reached up to 26.3% in the last few years, and its potential has already surpassed everyone’s expectations in multiple fields like photovoltaics, photoelectronics, lasers, scintillators, etc. But, its use in photo organic chemistry just started and we believe this typical promising material is going to fetch a new era in the field of organic photocatalysis. This comprehensive review systematically summarizes the development made over CsPbX3 perovskite catalysis in the last few years by assembling pieces of literature on perovskite-based organic reactions. And also, explores the intricacies of the underlying mechanistic cycles and discusses limitations with future scope of exploration
