Abstract : Prerequisite to the logical design of efficient chemiluminescent systems is the detailed knowledge of the fundamental excitation steps in known chemiluminescent processes. The study of the unimolecular thermal decomposition of 1,2-dioxetanes, subsequent to the isolation and characterization of the first dioxetane in 1969, has provided considerable insight into the chemistry of this ring
摘要:高效化学发光系统的逻辑设计的先决条件是详细了解已知化学发光过程中的基本激发步骤。在 1969 年分离和表征第一个二氧杂环丁烷之后,对 1,2-二氧杂环丁烷的单分子热分解的研究为该环系统的化学提供了相当多的见解。研究 1,2-二氧杂环丁烷的激发过程的主要重点是确定那些控制总激发态产率和三重态与单重态激发态产物比例的因素(高能、几何、Franck-Condon) . 任何假定的激发机制都必须考虑到相对较高的活化能,有效生产 eta pi 激发态含羰基产物,
