The effects of intermolecular and intramolecular triplet quenchers and sensitizers on the photochromism of nitrospiropyran have been examined in order to clarify the role of the triplet state (3A*) as well as that of the excited singlet state (1A*). The rates of photocoloration and fatigue were significantly affected: the quenchers retarded both rates, while the sensitizers retarded the former but
为了阐明三线态 (3A*) 和激发单线态 (1A*) 的作用,已经检查了分子间和分子内三线态猝灭剂和敏化剂对硝基螺吡喃光致变色的影响。光着色和疲劳的速率受到显着影响:淬灭剂延迟了这两种速率,而敏化剂延迟了前者但提高了后者的速率。可以得出结论,光稳定状态下光部花青素总量的 90% 以上是由 1A* 产生的,疲劳主要通过 3A* 进行。
