One-pot synthesis of hierarchically integrated covalent organic framework heterojunctions for photocatalysis (opens in new tab)

Covalent organic frameworks (COFs) with crystalline networks and large surface areas provide an ideal platform to mimic natural structures for photosynthesis. However, it remains challenging to construct complex, multistate architectures using single-component COFs. Herein, inspired by leaf morphology, we demonstrate a one-pot synthesis for constructing a one-dimensional (1D) COF and a three-dimensional (3D) COF from identical binary monomers, yielding a hierarchically integrated COF heterost...
