摘要
以4-[(8-羟基-5-喹啉)偶氮]苯磺酸与氯化锌为原料,采用溶剂热法通过原位反应合成标题配合物,并通过X-射线单晶衍射、红外光谱、元素分析和粉末X-射线衍射等方法对其进行了表征。标题配合物中两个5-硝基-8-羟基喹啉与Zn离子配位形成离散结构,通过两种C—H…O氢键将标题配合物连接形成二维层状结构,相邻层之间借助喹啉环间的两种π…π堆积相互作用将二维超分子层状结构沿c轴连接形成了三维超分子网络结构。荧光光谱表明,标题配合物为配体到配体的跃迁,跃迁过程中伴随有分子内电荷转移。
One new coordination polymer based on 4-[（ 8-hydroxy-5-quinolinyl） azo]-benzoic acid and Zn Cl2 was solvothermally synthesized via reaction in-situ and structurally confirmed by single-crystal X-ray diffraction,infrared spectrometry,elemental analysis and power X-ray diffraction（ PXRD）. Two 5-nitro-8-hydroxyquinolinne molecules and Zn cautions in the title complex were discrete structure,which were linked into two-dimensional（ 2D） layer structure by two kinds of C—H…O hydrogen bonds. Along c axis,2D layers were linked into a three-dimensional（ 3D） supramolecular network by two kinds of π…π interactions between quinoline rings. Fluorescence spectra showed that the title complex was ligand to ligand transition and had intramolecular charge transfer in the process of transition.
