摘　　要：合成了一种吲哚啉螺吡喃3,3-二甲基-N-溴丁基-ɑ-磺酸基苯并吲哚啉螺萘并吡喃,采用IR、~1H NMR以及MS对其结构进行了表征,利用升温IR,升温UV-Vis以及DSC研究了其热色性。结果显示该目标产物具有较为明显的热致变色性能。在温度升高到140°C左右时,能从浅绿色变为深绿色。The title compound 3,3-dimethyl-N-brombutyl-ɑ-sulfobenzo[e]indolinespironaphthopyran has been synthesized through a series of reaction.The structure of the compound is characterized by IR,1H NMRand MS.By means of UV-vis,IR spectrometers and DSC curves,the thermochromism are researched.The results indicate that the title compound shows thermochromicm.When the compound is heated to 140°C,it changes from pale green to deep green.Furthermore,the color change is reversible.
