The synthesis, structure and anion‐recognition properties of a new strapped‐porphyrin‐containing [2]catenane anion host system are described. The assembly of the catenane is directed by discrete chloride anion templation acting in synergy with secondary aromatic donor–acceptor and coordinative pyridine–zinc interactions. The [2]catenane incorporates a three‐dimensional, hydrogen‐bond‐donating anion‐binding
描述了一种新的含带卟啉的[2]环烷阴离子宿主系统的合成,结构和阴离子识别特性。链烷的组装是由离散的氯离子模板指导的,该模板与仲芳族供体-受体和配位吡啶-锌的相互作用协同作用。[2] catenane包含一个三维,氢键给体的阴离子结合袋。链烷·氯化物配合物的固态结构分析表明,氯阴离子通过六种会聚的CH·····Cl和NH···Cl氢键相互作用和溶液相1封装在链烷的互锁结合腔内。1 H NMR滴定实验表明,这种互补的氢键排列有助于在DMSO溶液中选择性识别较大的卤化物阴离子上的氯。
