Abstract
The discovery of new structures is very important for metal–organic framework (MOF) adsorbents and their application in gas separation, where the design of ligands and the selection of metal ions play a decisive role. Herein, we synthesized two isoreticular Zn-MOFs, UPC-250 and UPC-251, composed of imidazole-based tricarboxylic acid ligands and binuclear zinc clusters. The pore environment was regulated via modifying fluorine atoms at different positions of ligands, and one-step purification of ethylene from acetylene/ethylene/ethane ternary mixture was realized in UPC-251.
期刊介绍：
Inorganic Chemistry publishes fundamental studies in all phases of inorganic chemistry. Coverage includes experimental and theoretical reports on quantitative studies of structure and thermodynamics, kinetics, mechanisms of inorganic reactions, bioinorganic chemistry, and relevant aspects of organometallic chemistry, solid-state phenomena, and chemical bonding theory. Emphasis is placed on the synthesis, structure, thermodynamics, reactivity, spectroscopy, and bonding properties of significant new and known compounds.
