近期，福建师范大学范曦、项生昌、张章静等提出了一项创新策略。该策略通过利用卤键和特殊的共价B-N键的协同作用，首次成功构建了两例适用于SXRD精确测定结构的大尺寸单晶二维卟啉基有机聚合物。这些单晶在无需使用牺牲剂的情况下，能够高效地进行光催化，将水和 ...

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

Two-dimensional covalent organic frameworks (2D COFs) are highly porous organic materials with significant potential in catalysis, energy storage, and gas storage. These frameworks consist of ...

The layers are then stacked together, producing a layered solid. Since this structure differed from both conventional 2D-COFs and 3D-COFs and did not match prior classifications, the researchers ...
