Four isostructuralmetal–organicframeworks (MOFs) with various functionalized pore surfaces were synthesized from a series of diisophthalateligands. These MOFs exhibit a new network topology of 4.64.8}242.64}64.82}266}. 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
Metal–organic polyhedral frameworks are attractive in gas storage and separation due to large voids with windows that can serve as traps for guest molecules. Introducing multivariant/multicomponent functionalities in them are ways of improving performances for certain targets. The high compatibility of organic linkers can generate multivariant MOFs, but by far, the diversity of secondary building units
