| Abstract: | A new approach has been realized to construct a three‐dimensional doubly interpenetrated cubic metal–organic framework Zn2(PBA)2(BDC) ? (DMF)3(H2O)4 ( UTSA‐36 , HPBA=4‐(4‐pyridyl) benzoic acid, H2BDC=1,4‐benzenedicarboxylic acid) through the self‐assembly of the pyridylcarboxylate linker 4‐(4‐pyridyl) benzoate and bicarboxylate linker 1,4‐benzenedicarxylate with paddle‐wheel Zn2(COO)4]. The activated UTSA‐36 a exhibits highly selective gas sorption of C2H6, C2H4 and C2H2 over CH4 with the Henry law’s selectivities of 11 to 25 in the temperature range of 273 to 296 K attributed to the unique 3D intersected pore structure of about 3.1 to 4.8 Å within the framework, indicating that UTSA‐36 a is a potentially very useful and promising microporous material for such industrially important separation of C2 hydrocarbons over methane. |
