Gate-Opening Effect in a Flexible Metal-Organic Framework for Sieving Acetylene.

ABSTRACT: Adsorptive separation employing porous materials is one of the most promising alternative technologies for C₂H₂ purification due to its energy-efficient and environmentally friendly advantages. Herein, we present the design and synthesis of a dicopper-paddle-wheel-based metal-organic framework (termed JNU-5-Me) with a carboxylate-azolate organic linker. The use of such a linker results in the axial positions of the dicopper paddle wheels being occupied by azolates, and therefore, a much-improved chemical stability of the framework structure. JNU-5-Me shows negligible adsorption of C₂H₄, C₂H₆, and CO₂ at 1.0 bar and 298 K, while a gate-opening effect for C₂H₂ and a large C₂H_2</
