efficiency, and that dioxetane 1aA exhibited chemiluminescence with the highest efficiency among those for the oxynaphthyl-substituted dioxetanes hitherto known. The significant change in chemiluminescent efficiency depending on the substitution pattern was clarified to be attributed to the marked change in singlet-chemiexcitation efficiency for charge-transfer-induced chemiluminescence (CTICL) of 1aA–1eA
合成了5个带有2-羟基萘基的双环二氧杂环丁烷1aA - 1eA,并使用四丁基氟化铵(TBAF)作为DMSO中的碱检查了它们的化学发光分解。发现这些二氧杂环丁烷完全保持了作为萘环上的引发剂的羟基的取代模式与其化学发光效率之间的'奇/偶'关系,并且二氧环乙烷1aA在迄今为止已知的氧萘基取代的二氧杂环丁烷中,化学发光显示出最高的化学发光效率。化学发光效率的显着变化取决于取代模式,已明确归因于1aA – 1eA电荷转移诱导的化学发光(CTICL)的单重态化学激发效率的显着变化。关于CTICL分解的速率,观察到1aA – 1dA的“奇/偶”关系。
