Selective gas adsorption and fluorescence sensing response of a Zn(ii) metal–organic framework constructed by a mixed-ligand strategy

Abstract

By means of a mixed-ligand strategy, a novel bi-functional metal–organic framework, [H₂N(CH₃)₂]·Zn(NDC)(atz)·H₂O (NDC = 2,6-naphthalenedicarboxylic acid, Hatz = 1H-tetrazol-5-amine), was synthesized, which displays a three-dimensional two-fold interpenetrated framework. Owing to the introduction of two different functional organic ligands, this complex exhibits bi-functional properties, i.e., selective gas adsorption of CO₂ over CH₄ and fluorescence sensing response for nitrobenzene.
