共价有机框架（COF）是一类由分子前体通过共价键组装而成的新兴晶态有机多孔材料，在诸多领域具有广泛应用。相较于刚性COF，动态COF能够发生结构的动态转变，展现出更多功能。但动态COF设计和结构表征难度大，相关研究仍处于初步阶段。从结构上分析，二维片 ...

A deeper understanding of layer stacking could enhance synthesis methods, enabling the fabrication of larger COF crystals. While there has been substantial progress in synthesizing monolayer 2D ...

Imaging bilayer COFs in solution reveals mechanisms of moiré superlattice formation, advancing understanding of stacking in covalent organic frameworks.

STM images of (a) untwisted bilayer COF assembled from 2,7 PDBA; (b) twisted bilayer COF showing moiré superlattices, assembled from 1,6 PDBA. Disclaimer: AAAS and EurekAlert! are not responsible ...
