摘　　要：本工作以一水合乙酸铜、3-噻吩丙二酸和1,10-邻菲罗啉为原料,采用室温挥发法制备了一例噻吩羧酸铜配合物Cu-TMPE。该配合物为一维链状超分子结构,中心铜离子采取五配位模式,具有空的配位点,有利于吸附环境中的气体分子。以Cu-TMPE为敏感材料构建了化学电阻型气体传感器,并研究了其气敏特性。结果表明,基于Cu-TMPE的气体传感器在室温下对氨气显示了良好的响应特性。This work reported a copper-containing thiophene carboxylic acid complex Cu-TMPE using copper acetate monohydrate, 3-thiophene malonic acid, and 1,10-phenanthroline as raw materials based on a room-temperature volatilization method. The complex molecule has a one-dimensional chain-like structure, and the central copper ion adopts a five-coordinated mode, with empty coordination sites, which is conducive to adsorbing small gas molecules from the environment. An impedance-type gas sensor was constructed using Cu-TMPE as a sensitive material, and its gas sensing characteristics were tested and studied. The results indicate that the gas sensing device based on Cu-TMPE exhibits good gas sensing performance for ammonia gas.
