Assembly of metal–organic polyhedra into highly porous frameworks for ethene delivery†
Abstract
Two new mesoporous metal–organic frameworks (DUT-75 and DUT-76) with exceptional ethene uptake were obtained using carbazole dicarboxylate based metal–organic polyhedra as supermolecular building blocks. The compounds have a total pore volume of 1.84 and 3.25 cm3 g−1 and a specific BET surface area of 4081 and 6344 m2 g−1, respectively, and high gas uptake at room temperature and high pressure.
