Owing　to　the　critical　industrial　value,　the　applications　of　MOFs　in　the　field　of　light　hydrocarbon　gases　storage　and　separation　have　attracted　increasing　attention.　In　this　work,　a　microporous　material,　which　is　composed　of　typical　dicopper　paddlewheels　and　diisophthalate　ligands,　has　been　successfully　synthesized.　It　exhibits　good　gas　separation　ability　for　C2H2/CO2　mixtures　and　C2H6/CH4　mixtures,　respectively.　Confirmed　by　the　breakthrough　experiments,　the　separation　time　of　C2H2/CO2　mixtures　(50/50)　and　C2H6/CH4　mixtures　(15/85)　can　reach　up　to　36　and　95　min/g,　respectively　(gas　flow　rate　=　2　cm(3)/min).
