gelator. The metallohydrogel exhibits pH‐responsive nature as well as chemical responsiveness. Besides, it shows rapid thixotropic behavior when external mechanical forces are applied. The metal–organic hydrogel can be used as a heterogeneous catalyst for the reaction of SO2 and CO2 with epoxides to produce cyclic 1,3,2‐dioxathiolane‐2‐oxides and carbonates, respectively. The conversions were found to be
使用基于氨基酸的配体Na 2 HL H 3 L = 2-((3,5-二叔丁基-2-羟基苄基)氨基琥珀酸}}合成了铜金属有机水凝胶(MOG)作为胶凝剂。金属水凝胶具有pH响应性和化学响应性。此外,当施加外力时它表现出快速的触变性。金属有机水凝胶可用作SO 2和CO 2与环氧化物反应分别生成环状1,3,2-二氧杂硫杂环戊烷-2-氧化物和碳酸盐的非均相催化剂。发现转化率取决于环氧化物侧链的大小和类型。
