1.2-二甲基-3-吲哚甲叉(异丙叉)丁二酸酐(1)(C_(18)H_(17)NO_3)与1.2-二甲基-3-吲哚乙叉(异丙叉)丁二酸酐(2)(C_(19)H_(19)NO_3)同属于吲哚俘精酸类化合物,它们的分子结构非常类似,只是(1)中为吲哚甲叉,(2)中为吲哚乙叉.但它们的光色性却差别很大.化合物(1)无光致变色性,化合物(2)则表现为良好的光致变色性.其原因在于结构的不同。
(1) (C_ (18) H_ (17) NO_3) and 1.2-dimethyl-3-indolylidene difluoride (2) (C_ (19) H_ (19) NO_3) belong to indole fulgides, and their molecular structures are very similar except that (1) they are indole methine, (2) However, their photochromic properties are quite different: Compound (1) has no photochromic properties and Compound (2) shows good photochromism due to its structural difference.
