Owing to the intrinsically low dielectric properties, robust Coulomb interactions between photoinduced electrons and holes lead to dramatically strong exciton effects in polymeric photocatalysts. Such effects endow polymeric matrixes with nontrivial photoexcitation processes determining photocatalytic energy utilization. In this Minireview, we describe recent progress in the investigation of the excitonic effect in polymeric photocatalysts. On the basis of the understanding of excitonic effects in polymeric systems, we outline the relationships between excitonic behaviors and photocatalytic performance. Advances in optimizing the excitonic effect for gaining high‐efficiency polymer‐based photocatalysis are summarized. We also discuss the challenges in the field and forecast the directions for future research.
