The latest research by Professor Wang Cheng's team from the College of Chemistry and Molecular Sciences at Wuhan University (WHU) has been published in the Journal of the American Chemical Society. The study introduces a novel dynamic covalent organic framework (COF) with an interpenetrated 2D layered structure.  

WHU's doctoral students Cheng Yuanpeng and Peking University's Du Honglin are the paper's first authors, with Professor Wang Cheng, Associate Researcher Gui Bo, and Professor Sun Junliang from Peking University as corresponding authors.  

WHU's team introduces a novel dynamic covalent organic framework with an interpenetrated 2D layered structure.

COFs are a rapidly emerging class of organic porous materials with wide-ranging applications. Unlike rigid COFs, dynamic COFs can undergo structural transformations, unlocking new functionalities. However, their design and characterization remain challenging.  

Building on previous research, the team synthesized a highly crystalline COF capable of dynamic structural transitions in response to organic solvent vapors. Continuous rotation electron diffraction analysis revealed that vapor adsorption triggers anthracene ring rotation, leading to adjustments in the layered structure and significant changes in the framework's pore channels.  

The findings expand design strategies for dynamic COFs and open new avenues for developing functional interpenetrated COFs.
