comprehensive characterization of a systematic series of cleft‐type anion receptors imbedded into a polymeric architecture is presented. For the first time, isothermal calorimetric titrations on polymeric halogen‐bond‐based donors were exploited to evaluate the dependence of the anion affinity on different key parameters (i.e. monomeric versus polymeric receptor, halogen versus hydrogen bonding, charge assistance)
介绍了嵌入聚合物结构中的一系列系统型裂隙型阴离子受体的合成和全面表征。首次利用等温量热滴定法对基于聚合物卤素键的供体进行了评估,以评估阴离子亲和力对不同关键参数(即单体对聚合物受体,卤素对氢键,电荷辅助)的依赖性。这些供体体系与带有羧酸酯基团的共聚物的结合导致超分子交联的聚合物网络表现出出色的固有自我修复行为。利用FT拉曼光谱和纳米压痕测量来阐明基于卤素键形成的热诱导自愈机理。
