Four isostructural metal–organic frameworks (MOFs) with various functionalized pore surfaces were synthesized from a series of diisophthalate ligands. These MOFs exhibit a new network topology of {4.6 4 .8} 2 {4 2 .6 4 }{6 4 .8 2 } 2 {6 6 }. Hydrogen uptake as high as 2.67 wt % at 77 K/1 bar and CO 2 uptake of 15.4 wt % at 297 K/1 bar have been observed for PCN‐308, which contains CF 3 groups. The isostructural series of MOFs also showed reasonable adsorption selectivity of CO 2 over CH 4 and N 2 .
