Control over interpenetration in lanthanide-organic frameworks: synthetic strategy and gas-adsorption properties.

摘要: Two isostructural lanthanide−organic frameworks (1 and 2) with 2-fold interpenetrating nets have been synthesized based on 1,4-benzenedicarboxylic acid (H2BDC). By application of an organic ligand hindrance groups a terminal chelating to replace BDC coordinated solvates, interpenetration has effectively controlled. The gas-sorption properties the noninterpenetrating net studied.
