Development of a supramolecular ensemble of an AIEE active hexaphenylbenzene derivative and Ag@Cu2O core–shell NPs: an efficient photocatalytic system for C–H activation

Abstract

A supramolecular ensemble having Ag@Cu₂O core–shell nanoparticles stabilized by aggregates of a hexaphenylbenzene derivative has been developed which exhibits excellent photocatalytic efficiency in reactions involving preparation of imidazole and benzimidazole derivatives via C–H activation.
