Abstract
The synthesis and characterization of two novel chromium(II)-based cuboctahedral metal-organic polyhedra is reported. The alkane functionalized analog, Cr_tBu-bdc (tBu-bdc = 5-tertbutylbenzene-1,3-dicarboxylate) exhibits excellent thermal stability, retaining high porosity above 548 K. Upon activation at 448 K, the material achieves a metal-organic polyhedra record Langmuir surface area of 1796 m2/g (1135 m2/g BET). Cr_tBu-bdc also exhibits excellent O2/N2 selectivity adsorbing 5.3 mass % and 0.11, respectively, at 298 K and 100 kPa.Citation
