【摘要】 与其它类光致变色化合物相比 ,本文合成的吲哚螺嗪类光致变色化合物 ,具有良好的热稳定性、抗疲劳性、耐久性和能反复使用等特点。该化合物在紫外光照射下 ,颜色由无色变成蓝色 ,再用红外光照射或置于暗处 ,颜色变回到无色。通过合成实验 ,找出了产率高、方法较合理的反应流程。进行配墨和制膜实验 ,结果表明其显色性、灵敏度及耐久性均较理想。更多还原

【Abstract】 In this thesis,photochromic compound of spiroindolinonaphthoxazine is synthesized As compared to other photochromic compounds,it possesses a good thermal stability and remarkable fatigue resistance,so its durability is good,and can be used repeatedly,etc By synthetic study,we have found the reaction process with high yield and the rational method The further experiments on mixing ink and on preparing film are made,in order to examine the developing color,sensitivity and durability (durability in sun) Irradiated with ultravioletray,its color change takes place from invisible to blue When irradiated with infrared ray or in dark,its color resumes invisible更多还原
