Structural self-assembly enables the hydrogen-bonded organic frameworks (HOFs) with facile synthesis, self-repair structures, and intriguing optoelectronic attributes. Herein, we report a strategy that directly employs HOF monomer for efficient photoredox catalysis without involving catalyst prefabrication. Remarkably, this simplified mode was equally effective as prefabricated catalysts, verified high activity, selectivity, generality in photocatalytic sulfide oxygenation. The complementary hydrogen (H) bonds of carboxy dimmers led to fast situ into target framework. yield enhancement singlet oxygen (1O2) resulting from excitonic effect strong interlayer confinement accounted activity origin. This work offered but application approach use material catalysis.
