摘要

二维（2D）共价有机骨架（COFs）通常被认为具有刚性的面内孔。在这项研究中，我们成功地合成了一系列二维COFs (NUS 126-128)，其特征是在整个网络中交错排列AB堆叠。这些二维COFs在客体分子存在下表现出平面内孔隙的可逆动态行为，表现出在大孔（lp）和窄孔（np）之间可逆切换的孔隙呼吸行为。这种孔隙呼吸行为归因于COFs与溶剂分子之间的相互作用。

Guest-Induced Self-Adaptive Pore Dynamic Behaviour of 2D Covalent Organic Frameworks

Two-dimensional (2D) covalent organic frameworks (COFs) are typically regarded as having rigid in-plane pores. In this study, we successfully synthesized a series of 2D COFs (NUS 126-128) characterized by a staggered AB stacking arrangement throughout the network. These 2D COFs exhibit a reversible dynamic behavior of their in-plane pores in the presence of guest molecules, displaying pore breathing behavior with a reversible switch between large pores (lp) and narrow pores (np). This pore-breathing behaviour is ascribed to the interaction between COFs and solvent molecules.
