摘要/Abstract

摘要： 以1，3，5-苯三甲酸（H₃BTC）为配体， Ni²⁺为中心离子，水为溶剂，常温下合成均苯三甲酸-镍配合物（BTC-Ni），通过X射线单晶衍射表征其晶体结构，研究其频率特性、响应恢复特性和湿滞特性等湿敏性质，并对其感湿机理进行测试和分析. 结果表明：该晶体单元结构为［Ni₃(BTC)₂·14H₂O］·2H₂O（CCDC编号：1990438），配合物为零维结构；在中高湿度（54%~97% RH）区域的感湿特征曲线线性关系良好，响应恢复时间为2 s，湿敏性能优异，适用于作为检测中高湿度环境的湿敏材料.

Abstract: The complex of trimesic acid-nickel was synthesized at room temperatuer with 1,3,5-benzoic acid as ligand, Ni²⁺ as center ion and water as solvent. X-ray diffraction was used to characterize the crystal structure. We studied the frequency characteristics, response recovery characteristics and humidity sensing characteristics, tested and analyzed the humidity sensing mechanism. The results show that the crystal unit structure is ［Ni₃(BTC)₂·14H₂O］·2H₂O(CCDC: 1990438), and the complex has zero dimensional structure. The linear relationship of humidity sensitive characteristic curve is good in the medium and high humidity area（54%—97% RH）, the recovery time is 2 s, and the humidity sensing performance is excellent, which is suitable for the detection of humidity sensing materials in medium and high humidity environment.

Key words: trimesic acid, metal-organic coordination compound, humidity sensing
