A copper metal–organic hydrogel (MOG) has been synthesized using an amino acid‐based ligand, Na 2 HL {H 3 L = 2‐{(3,5‐di‐ tert ‐butyl‐2‐hydroxybenzyl)amino succinic acid} as a 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 SO 2 and CO 2 with epoxides to produce cyclic 1,3,2‐dioxathiolane‐2‐oxides and carbonates, respectively. The conversions were found to be dependent on the size and type of the side chain of the epoxides.
