A novel microporous hydrogen-bonded framework with electron-rich alkynyl groups for highly efficient C2H6/C2H4 separation

A novel electron-rich alkynyl-functionalized HOF material was designed and synthesized for efficient C 2 H 6 /C 2 H 4 separation. The alkynyl groups serve as functional binding sites to result in high C 2 H 6 adsorption capacity and selectivity.
