Abstract

Reactions of divalent metal salts with 4,4-oxybis(N-(pyridine-4-yl)-benzamide), , and naphthalene-1,4-dicarboxylic acid (1,4-HNDC) in various solvents gave [Zn()(1,4-NDC)·HO], , [Cd()(1,4-NDC)(HO)·MeOH], , and [Co()(1,4-NDC)(HO)·MeOH], , which have been structurally characterized. Complexes - show eight-fold interpenetrating frameworks with the topology, which exhibit porosities substantiated by CO adsorption, whereas and manifest stability in aqueous environments and show high selectivity toward sensing of mesitylene molecules and Fe ions with low detection limits and good reusability up to five cycles.

摘要

二价金属盐与4,4'-氧双（N-（吡啶-4-基）-苯甲酰胺）以及萘-1,4-二甲酸（1,4-HNDC）在各种溶剂中的反应生成了[Zn( )(1,4-NDC)·H₂O]、[Cd( )(1,4-NDC)(H₂O)·MeOH]和[Co( )(1,4-NDC)(H₂O)·MeOH]，这些配合物已通过结构表征。配合物 - 显示出具有拓扑结构的八重互穿框架，通过CO吸附证实其具有孔隙率，而和在水环境中表现出稳定性，并且对均三甲苯分子和Fe离子的传感具有高选择性，检测限低且高达五个循环具有良好的可重复使用性。
