Polarization-induced exciton dissociation in COF photocatalyst

Abstract

The regulation of the exciton properties is crucial for enhancing the activities of polymeric photocatalysts. In this issue of Chem Catalysis , Wang’s group introduces an interesting strategy that integrating ionic moieties into a covalent organic framework (COF) can increase the dielectric constant of the organic semiconductor, facilitate the exciton dissociation, and thereby boost visible-light-driven photocatalytic production of hydrogen peroxide as a solar fuel from reducing dioxygen.
