溶剂控制的铜基金属-有机框架物的合成与荧光性能
Solvent-Dependent Synthesis and Fluorescent Properties of Cu(Ⅱ) Metal-Organic Frameworks
摘要
Abstract
Metal-organic frameworks have promising potentials of for applications in the areas of fluorescence recognition.To explore more accurate identification of synthetic substancess, we synthesized two copper metal-organic frameworks(MOFs), {[Cu(PAIA)(H2O)]·2H2O}(1) and {[Cu3(PAIA)2(DMSO)(Pyridine)1.5]}(2)(H2PAIA=5-(propionyl-λ2-azanyl)isophthalic acid;DMSO=dimethyl sulphoxide), by the solvothermal reaction in the presence of H2PAIA under different solvents(H2O and DMSO/H2O).Synthetic investigations and structural analyses reveal that both MOFs show distinct frameworks with remarkable solvent-directed feature, although they are assembled from the same starting materials, i.e., Cu(NO3)2·3H2O with H2PAIA for complexes 1 and 2.The topological structures and fluorescent properties of the two coordination compounds show a significant difference.Complex 1 is a three-dimensional NbO-type topology, while the complex 2 is a two-dimensional sql-type topology.Complex 1 exhibits fluorescent recognition to both Pb2+ and Ag+ ions, while complex 2 exhibits fluorescent recognition of Pb2+ ion.The water contact angle for complex 1 is 85.06°, while the water contact angle for complex 2 is 52.71°.关键词
