含钴配合物CoL合成及湿敏性能研究

Synthesis and Humidity Sensitivity of Cobalt Containing Complex CoL

摘要: 本文通过氯化钴和氮三乙酸为原料设计并合成了具有超分子结构的含钴配合物材料CoL。在该配合物分子中存在大量晶格水，进而和配体的羧酸氧靠氢键连接，形成稳定的三维氢键网络结构。鉴于该材料丰富的氢键结构，测试了其对水分的敏感性能。研究表明，基于CoL的传感器件具有良好的感湿性能。

Abstract: A cobalt complex material CoL with supramolecular structure was designed and synthesized from cobalt chloride and nitrotriacetic acid in this work. There is a large amount of lattice water in the complex molecule, which is then connected to the carboxylate oxygen of the ligand through hydrogen bonds, forming a stable three-dimensional hydrogen bond network structure. Given the rich hydrogen bonding structure of the material, its sensitivity to moisture was tested, and research shows that the CoL has good humidity sensing performance as a sensor component for humidity sensitive materials.
