Abstract

The dual-ligand strategy was employed to synthesize a new microporous material, [Zn₃(SNDC)(AmTAZ)₃(H₂O)]·H₂O·CH₃CN (1), incorporating sulfonic acid and amino groups for enhancing gas adsorption and separation. The activated 1 (named 1a) exhibited selective adsorption of acetylene over carbon dioxide and methane. Hence, the dual-ligand strategy optimized the pore environment and provided an effective approach for pure separation of gases.
