摘要：
A porous MOF platform (SNNU-65s) formed by creatively combining paddle-wheel-like [Cu-2(COO)(4)] andtrigonalprismatic [M-3(mu(3)-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.
