Ligand-elaboration as a strategy for engendering structural diversity in porous metal–organic framework compounds

Abstract

A series of 4,4′-ethynylenedibenzoic acids were synthesized and used in the construction of Zn-based, mixed-ligand metal–organic frameworks; through variation of functionality in the 3- and 3′-positions of these linkers, a collection of MOFs with differing connectivities and varying levels of interpenetration was obtained.
