Abstract

Aim The thermochromism of the title compound was studied.p-C6H4OHNO2·1.5H2O showed reversible thermochromism.When heated to 135 ℃,it turned from nacarat to bright red.When droped to room temperature,the color came back laxly.Method In situ elevated temperature ultraviolet spectrum and in situ elevated temperature IR as well as DSC-TG analysis confirmed the phenomenon.Results The methods as above made sure the reversible thermochromism owing to hydration and dehydration.Conlusion The title compound was a new type thermochromic functional material.
