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

摘要

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. The chemistry of metal-organic frameworks (MOFs) has matured to a stage where, together with the exploratory synthesis and characterization of new materials, there is a growing drive towards designing and synthesizing new materials specifically to study the influence of chemical functionality, catenation, and coordination environment on various MOF applications, e.g., gas uptake, separations, and catalysis.
