Abstract
ABSTRACT Covalent organic frameworks (COFs) have emerged as attractive platforms for solar‑driven H 2 O 2 production directly from pure water. However, conventional integrated active‑site architectures that couple oxygen reduction reaction (ORR) and water oxidation reaction (WOR) often suffer from inefficient photogenerated charge separation and severe recombination. Here, we propose a functionality‐coupled spatial separation strategy that integrates site‑isolated redox domains with an anthraquinone (AQ) redox‑shuttle characteristics, exemplified by an AQ‑functionalized COF (BTT‑AQ). Combined experimental and theoretical studies reveal that the benzotrithiophene (BTT) domain acts as a selective two‑electron…
