为了获得新型功能材料，合成了无色亚甲基蓝成色剂3，7-双（二甲氨基）-10-（邻硝基苄氧羰基）吩噻嗪（4）和3，7-双（二甲氨基）-10-（叔丁氧羰基）吩噻嗪（5）。化合物（4）和（5）在乙腈中的紫外光照射下表现出良好的显色反应。4的二甲基亚砜（DMSO）溶液通过在对甲苯磺酸存在下在70 °C下加热显示出很小的变化。另一方面，5的DMSO溶液在相同条件下显示蓝色。4或5的乙腈溶液经7次照射后未变蓝。
Leuco methylene blue color formers, 3,7-bis(dimethylamino)-10-(o-nitrobenzyloxycarbonyl)phenothiazine (4) and 3,7-bis(dimethylamino)-10-(tert-butoxycarbonyl)phenothiazine (5) were synthesized in order to obtain novel functional materials. These compounds, (4) and (5), showed good coloring reaction in acetonitrile by UV irradiation. The dimethylsulfoxide (DMSO) solution of 4 showed little change by heating at 70 °C in the presence of p-toluenesulfonic acid. On the other hand, the DMSO solution of 5 showed the blue coloration under the same condition. The acetonitrile solutions of 4 or 5 did not change to blue by 7 irradiation.
