Efficient C 2 H 2 -selective separation in a microporous Zn( ii )-based metal–organic framework via the dual-ligand strategy

A new microporous Zn( ii )-based MOF 1 has been successfully synthesized by utilizing both amino- and nitro-functionalized ligands. Gas sorption explorations reveal that the activated sample exhibits significant C 2 H 2 uptakes and selective capture from CO 2 .
