Four isostructural metal-organic frameworks (MOFs) with various functionalized pore surfaces were synthesized from a series of di-isophthalate ligands. These MOFs exhibit a new network-topology of {4.64.8}2{42.64}{64.82}2{66}. Hydrogen Uptake as high as 2.67 wt% at 77 K/1 bar and CO2 uptake of 15.4 wt% at 297 K/1 bar have been observed for PCN-308 , which contains �CF3 groups. The isostructural series of MOFs also showed reasonable adsorption selectivity of CO2 over CH4 and N2
