A guest-induced reversible crystal-structure transformation is identified in a new 3D covalent organic framework (COF) by comprehensive analyses using powder X-ray diffraction, organic vapor sorption isotherm, and Xe NMR spectroscopy. The revolving imine bond in interpenetrating 3D networks is uncovered as the key to the dynamic behavior, the potential applications of which are illustrated by gas separation and heterogeneous catalysis, thus paving the way to the design of stimuli-responsive and multifunctional COF materials.
通过粉末X射线衍射、有机蒸汽吸附等温线和氙核磁共振光谱等综合分析，在一种新型三维共价有机框架（COF）中发现了客体诱导的可逆晶体结构转变。互穿三维网络中旋转的亚胺键被揭示为这种动态行为的关键，其潜在应用通过气体分离和多相催化得到了说明，从而为刺激响应型和多功能COF材料的设计铺平了道路。
