Isostructural metal-organic frameworks assembled from functionalized diisophthalate ligands through a ligand-truncation strategy. uri icon

abstract

  • 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 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 .
