Realizing the Potential of Acetylenedicarboxylate by Functionalization to Halofumarate in Zr^IV Metal–Organic Frameworks

Abstract

A strategy was developed to obtain from acetylenedicarboxylic acid either an acetylenedicarboxylate-based Zr^IV metal-organic framework (MOF) with fcu topology or a halo-functionalized-MOF-801 through in situ ligand hydrohalogenation. The new materials feature exceptionally high hydrophilicity and CO₂ /H₂ adsorption energetics. The acetylenedicarboxylate linker and its functionalizable triple-bond discloses its potential in the engineering of microporous materials with targeted properties.
