A novel low density metal–organic framework with pcu topology by dendritic ligand

Abstract

A novel low density two-fold interpenetrated MOF-5 analogue with pcu topology, JUC-100, was designed and prepared successfully. It can be regarded as MOF-5 in which half of the Zn(4)O(CO(2))(6) units are replaced by organic 1,3,5-triphenylbenzene segments. JUC-100 exhibits H(2) uptake ability comparable to interpenetrated MOF-5, but relatively low initial isosteric heat of adsorption.
