  热不可逆光致变色系统。非对称二芳基乙烯衍生物的可逆光环化

  摘要：

  合成了一端为吲哚环、双键另一端为噻吩、苯并[b]噻吩或吡咯环的非对称二芳基乙烯，试图获得具有更长吸收带的热不可逆光致变色化合物波长。2-(1,2-Dimethyl-3-indoyl)-3-(2,4,5-trimethyl-3-thienyl)maleic anhydride(8a) 经历了光致环化/开环反应，量子产率相对较高（环化量子产率：0.15；开环量子产率：0.40），两种异构体都是热稳定的。闭环形式在 595 nm 处具有最大吸收，边缘延伸至 760 nm。8a 和 2-(1,2-二甲基-3-吲哚基)-3-(2-甲基-3-苯并[b]噻吩基)马来酸酐 (9a) 的环化/开环反应是由 Ar 离子诱导的 (488 nm) 和 He-Ne (633 nm) 激光器。

  An ink that may be used in ink jet devices is a photochromic ink comprising an ink vehicle that includes at least one radiation curable component, at least one photochromic material and at least one photoinitiator. The ink is cured via exposure to radiation that cures the at least one radiation curable component of the ink. A radiation curable ink capable of exhibiting photochromatic color changes, which may be used to indicate a document's authenticity, is thus achieved.
