Unlocking Long-Range Exciton Diffusion via Hydrogen-Bonded-to-Covalent Organic Framework Transformation for Photocatalytic H2O2 Synthesis.
Controlling long-range exciton diffusion remains a central challenge in organic photocatalysts because of the inherent trade-off between extended π-conjugation and long-range structural order. Here, we report a topochemical polymerization strategy that converts a single-crystalline hydrogen-bonded organic framework (HO...
