摘要
本文研究了BE(Ⅱ)-CAS 水溶液体系热致变色性能;探讨了酸度、温度等条件对体系热致变色性能的影响。实验结果表明该体系在特定条件下具有较明显的热致变色现象,且仅由配合物所产生,其特征是:体系受热时颜色由深色(玫瑰红)变为浅色(黄色);与RE(Ⅲ)-XO,RE(Ⅲ)-SXO 体系的色变趋向相反,达种差异性与螯合物分子的结构特征有关。
The authors studied systematically the thermochromic properties ofrare earth(RE)chelates of triphenylmethane complexons.The results showthat the ligand structure is an important factor affecting the thermochromicproperties and mechanisrns.To research the relation between the ligandstructure and thermochromic properties we studied in this paper the thermo-chromic characteristic of the RE(Ⅲ)-chrome azurol S chelates.
