摘要
越来越多有机热致变色材料的应用研究受到关注,不同材料的变色机理也不尽相同,将热敏红、不同显色剂和溶剂(十二醇)分别先后制备了二元复配物和三元复配物,通过观察复配物的红外光谱和热变色情况,重点研究分析了以热敏红为显色剂的三元体系可逆变色的机理,有机热致三元复配物的可逆变色依赖于分子间相互作用力的大小变化。
Abstract
More and more attention has been paid to the application research of organic thermochromic materials,and the discoloration mechanisms of different materials are different.In this paper,binary and ternary compounds were prepared with thermal red,different chromogenic agents and solvents (dodecanol),respectively.By observing the infrared spectrum analysis and thermochromism of the compounds,the reversible discoloration mechanism of ternary system with thermal red as chromogenic agent was mainly studied and analyzed.The reversibility of organic thermochromic ternary compounds depended on the change of intermolecular interaction force.
