Four isostructural metalorganic frameworks (MOFs) with various functionalized pore surfaces were synthesized from a series of diisophthalate ligands. These MOFs exhibit a new network topology of {4.64.8}2{42.64}{64.82}2{66}. Hydrogen uptake as high as 2.67wt% at 77K/1bar and CO2 uptake of 15.4wt% at 297K/1bar 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.
