Polymerized Small‐Molecule Acceptors with Linker Length‐Dependent Photocatalytic Activity for High‐Performance Solar Hydrogen Evolution

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 13, 2025

Abstract Developing organic semiconductor photocatalysts with alterable optical properties and excitonic behaviors for photocatalytic hydrogen evolution has received significant attention recently. Herein, three polymerized small‐molecule acceptors (PSMAs) different linker lengths, namely PY‐1T, PY‐2T PY‐3T, are designed synthesized to construct nano‐photocatalysts. In comparison YDT, these PSMAs exhibit broader absorption in both visible near‐infrared (NIR) light region as well enlarged exciton diffusion length. the meanwhile, intramolecular charge transfer separation is promoted by varying length, leading enhanced harvesting utilization. As a result, single‐component nano‐photocatalyst based on PY‐3T achieves an impressive average rate (HER) of 400.3 mmol h −1 g under AM 1.5G sunlight (100 mW cm −2 ), which ≈48 times greater than that YDT NPs (8.3 ). These results not only prove potential developing extended chain length efficient photocatalysts, but also elucidate importance regulating designing high‐performance photocatalysts.
