Abstract

A porous MOF platform (SNNU-65s) formed by creatively combining paddle-wheel-like [Cu₂(COO)₄] and trigonal prismatic [M₃(μ₃-O)(COO)₆] building blocks was designed herein. The mixed and high-density open metal sites and the OH-functionalized pore surface promote SNNU-65s to exhibit ultra-high C₂H₂ uptake and separation performance. Impressively, SNNU-65-Cu-Ga stands out for the highest C₂H₂/CO₂ (18.7) and C₂H₂/CH₄ (120.6) selectivity among all the reported MOFs at room temperature.
