摘要

在单一多孔配位聚合物（PCP）中实现多种可迁移构型以实现可切换功能一直是人们追求的目标。在本研究中，我们报告了通过设计可调节的框架内 π-π 堆叠分子，在一种多孔配位聚合物材料中实现多种构型的情况。我们证明，根据溶剂类型的不同，五氯苯酚可容纳三种不同的开放孔相。此外，根据活化方法的不同，这种五氯苯酚还表现出三种不同的封闭孔相，从而显示出不同的二氧化碳吸附特性。

Flexible Porous Coordination Polymer with Multiple Configurations for Guest Recognition and Switchable CO2 Sorption Properties

Realizing multiple metastable configurations in a single porous coordination polymer (PCP) has long been pursued to achieve switchable functionality. In this study, we reported multiple configurations in one PCP material via the design of the adjustable intraframework π-π stacking moieties. We demonstrated that the PCP can accommodate three different open pore phases depending on the type of solvent. Furthermore, this PCP exhibits three distinct closed pore phases depending on the activation approaches, demonstrating different CO2 sorption properties.
