To immobilize open Cu2+ sites and tune suitable pore spaces, we have realized a doubly interpenetrated metal鈥搊rganic framework (MOF) [Cu2L(H2O)2]路(DMF)6路H2O (ZJU-30, ZJU = Zhejiang University; H4L = biphenyl-3,3鈥?5,5鈥?tetra-(phenyl-4-carboxylic) acid; DMF = N,N-dimethylformamide) for the highly selective separation of C2 hydrocarbons over C1 methane with the Henry law鈥檚 selectivities from 9.58 to 29.8 in the temperature range from 273 to 298 K.
