Abstract The selective oxidative coupling of phenol derivatives, involving carbon‐carbon (C−C) and carbon‐oxygen (C−O) bond formation, has emerged as a critical approach in the synthesis natural products. However, achieving precise control over selectivity reactions unsubstituted phenols utilizing solar light driving force remains big challenge. In this study, we report series porous Cs 3 Bi 2 X 9 (X=Cl, Br, I) photocatalysts with tailored band gaps compositions engineered for efficient solar‐light‐driven coupling. Notably, p‐Cs Br exhibited about 73 % C−C coupling, displaying high formation rate 47.3 μmol g cat −1 h under radiation. Furthermore, enables site‐selectivity derivatives on , enhancing distinctive structure appropriate band‐edge positions facilitated charge separation, surface interaction/activation phenolic hydroxyl groups, resulting kinetically preferred C−O bond. Mechanistic insights into reaction pathway, supported by comprehensive experiments, unveiled crucial role interfacial transfers Lewis acid sites stabilizing intermediates, thereby directing regioselectivity diradical couplings unsymmetrical biphenols.

Abstract Metal halide perovskite quantum dots (QDs) are widely studied in the field of photocatalytic CO 2 due to their strong light absorption and long carrier migration length. However, it can not exhibit high catalytic performance because radiative recombination lack effective sites. organic frameworks (MOFs) encapsulated QDs only solve aforementioned problems, but also maintain own unique characteristics with ultra‐high specific surfaces area abundant metal In this work, lead‐free bismuth‐based into Zr‐based MOF (UiO‐66), which combines advantages power conversion efficiency surface porosity UiO‐66. addition, benefiting from close contact between Cs 3 Bi Br 9 UiO‐66 enables photogenerated electrons be rapidly transferred MOF.
