摘　　要：常温常压下,以硫酸亚铁和5-偶氮四唑水杨酸(H3ASA)为原料,构筑了一例新的基于H3ASA的铁配合物[Fe(H2ASA)2(H_(2)O)2]n(1)。通过单晶测试、XRD、红外、热重、荧光等方法对配合物的结构及性质进行表征,单晶解析表明配合物为一维链结构,直链间通过O-H×××O和O-H×××N两种氢键连接成三维超分子框架。光谱学测试表明配合物可发出紫色荧光,电化学测试结果表明负载配合物1的电极材料对多巴胺具有选择性响应,且不受干扰物质的影响。A new iron complex[Fe(H2ASA)2(H_(2)O)2]n based on 5-azotetrazolsalicylic acid(H3ASA)was constructed which were used Ferrous sulfate and 5-azotetrazole salicylic acid(H3ASA)as raw materials under the condition of atmospheric pressure.Characterized by single crystal structure test,X-ray powder diffraction test,infrared test,thermogravimetric test,fluorescence test and other test methods,the complex is one-dimensional chain structure throught by the O-H×××O and O-H×××N two hydrogen bonds into a 3d supramolecular framework.Spectroscopy tests showed that the complex could emit purple fluorescence.The electrochemical test results showed that the electrode materials loaded with the complex responded to dopamine and were not affected by the interfering substances.
