Organic Donor‐Acceptor Systems for Photocatalysis

Advanced Science, Journal Year: 2023, Volume and Issue: 11(10)

Published: Dec. 25, 2023

Abstract Organic semiconductor materials are considered to be promising photocatalysts due their excellent light absorption by chromophores, easy molecular structure tuning, and solution‐processable properties. In particular, donor‐acceptor (D‐A) type organic photocatalytic synthesized introducing D A units intra‐ or intermolecularly, have made great progress in studies. More more studies demonstrated that the D‐A combine effective carrier separation, tunable bandgap, sensitive optoelectronic response, an strategy for enhancing absorption, improving exciton dissociation, optimizing transport. This review provides a thorough overview of strategies aimed at performance semiconductors. Initially, essential methods modifying materials, such as interface engineering, crystal interaction modulation, briefly discussed. Subsequently, delves into various based on intramolecular intermolecular interactions, encompassing small molecules, conjugated polymers, crystalline supramolecules, heterojunctions. Meanwhile, energy band structures, dynamics, redox‐active sites under different bonding modes Finally, highlights advanced applications photocatalystsand outlines prospective challenges opportunities.
