摘　　要：本论文设计、合成了一种含萘环半刚性多羧酸配体,即为4,4'-(萘-1,5-二氧基)邻苯二甲酸。利用合成得到的含萘环半刚性多羧酸配体、辅配体和过渡金属离子通过溶剂热合成方法获得了一种新的钴配位聚合物[Co(L1)(1,4-bib)_(2)(H_(2)O)_(2)]_(n),并采用X-单晶衍射光谱、元素分析、傅里叶-红外光谱、粉末X-射线衍射等测试手段对配合物的晶体结构进行了表征。此外,研究了不同浓度的配体、配合物对超氧阴离子和羟基自由基的抑制作用,研究发现配合物对两种自由基的清除活性优于配体。A semi-rigid carboxylic acid ligand containing naphthalene ring,namely 4,4’-((decahydronpht-halene-1,5-diyl)bis(oxy))bis(cyclohexane-1,2-dicarboxylic acid)was synthesized.And a new cobalt coordination polymer[Co(L1)(1,4-bib)_(2)(H_(2)O)_(2)]_(n) was synthesized by using semi-rigid carboxylic acid ligand containing naphthalene ring,auxiliary ligand and transition metal ion,and the crystal structure was characterized by X-single crystal diffraction spectra,elemental analysis,fourier-infrared spectroscopy,powder X-ray diffraction.The inhibitory effects of different concentrations of ligands and complexes on superoxide anion and hydroxyl radical were studied,the results found that the scavenging activity of the complex was better than that of the ligand.
