Abstract

Abstract Severe exciton effect significantly hinders free‐charge‐involved water redox reactions, limiting the improvement of photocatalytic performance. Herein, a dual polarization strategy was proposed to achieve spontaneous exciton dissociation while lowering exciton binding energy by introducing B←N bonds and triazine as the dual‐type polarization unit into the alkynyl‐linked conjugated backbone. Dual‐type polarization centers can induce spontaneous exciton dissociation (exciton activation energy
