Photocatalytic hydrogen peroxide (H2O2) production using conjugated polymers as photocatalysts is a green and sustainable approach to synthesizing H2O2. Nevertheless, the efficiency still hindered by inefficient charge separation transfer dynamics. Herein, series of coplanar 2D ladder with different substituents were reported metal-free for artificial photosynthesis Detailed experimental theoretical investigations reveal that skeleton strong electron-withdrawing could profoundly facilitate transfer. Possessing these notable merits, cyano-substituted polymer (PAE-CN) exhibits remarkable photocatalytic performance on H2O2 evolution. This study contributes development effective tailored potential applications in photosynthesis.

Metal-anchored covalent organic frameworks (COFs), as a class of significant derivatives COFs, are widely used heterogeneous catalysts in diverse chemical reactions. However, they typically synthesized via post-treatment strategies, which often lead to the decline COF crystallinity, decrease porous properties, instability catalytic performances, generation additional waste, and consumption excess time energy.
