盐酸氨基脲缩水杨醛与CuCl2配合物的热色性研究

Thermochromic Behavior of Complex of Copper Coordination to 2-(2-hydroxybenzylidene) Hydrazinecarbox

摘要: 从盐酸氨基脲出发,经与水杨醛缩合,再与氯化铜配合等步骤,生成了席夫碱的配合物.目标化合物经IR、远红外光谱以及元素分析确证了分子结构,并通过差示量热扫描分析(DSC)测定了其变色的温度范围.升温时,在50~110℃有变色峰出现;降温时,在45~85℃出现变色峰.与目测法结果相符,证明该化合物是一新型可逆热致变色配合物.

Abstract: The title complex was synthesized and characterized.It underwent reversible thermo-chromism as temperature rose and went down.The title complex was characterized by elemental analysis and IR spectroscopy.The DSC measurement was recorded in dynamic air and interpreted.The results showed that the thermochromism was caused by the transformation of coordination number.
