  摘要：

  研究了 17 种不同取代形式的螺吲哚啉萘噁嗪在环己烷、甲苯、乙腈和甲醇的流体溶液中的光致变色和溶致变色行为。在连续单色辐照条件下，确定了封闭螺吲哚菁和开放美拉德菁形式的波长和摩尔吸收系数等具体参数，以及光变色和光漂白量子产率、热褪色速率常数和活化能。结果表明，这些参数大多与高度共轭的光致花青素上的电子分布以及它们的类醌或齐聚物特性密切相关。根据受体或供体的特性及其取代基的位置，可以检测到三类化合物。

  DOI：10.1016/s0040-4020(97)00640-6

  日期：1997.7

  A synthetic access to photochromic spirooxazines is developed through the condensation of methylene-substituted azaheterocycles on 1-amino-2-naphthols in presence of an oxidizing agent. Compared to usual preparation of this kind of compounds (via 1-nitroso-2-naphthols), yields are generally good and approaches to Further spiroheterocyclic oxazines are possible.
