【摘要】 对硝基苯酚是没有热色性的物质,本工作在水溶液中合成了水合对硝基苯酚,且培养出单晶。该结晶水合物表现出可逆的热色性,当加热到140℃时,它会由橙红色变为明亮的红色;随着温度缓慢降低,其颜色也恢复为原来的橙红色。差示扫描量热法(DSC)分析证实了这一观察到的现象。热重分析(TG)测试显示该结晶水合物颜色的变化是由于水合和失水而导致的。更多还原

【Abstract】 P-nitrophenol showed no sign of thermochromism.The title compound,p-nitro-phenol hydrate was synthesized in solution.It’s monocrystalline was cultivate.The hydrate showed reversible thermochromism.When heated to 140 ℃,it turned from salmon pink to bright red.While resuming,the color came back.DSC analysis confirmed the observed phenomenon.TG analysis made sure the color’s change owing to hydration or losing water.更多还原
