【 摘 要 】

The productionof visible light by chemical reactions constitutes interesting and fascinatingphenomena and several reaction mechanisms are discussed to rationalize excitedstate formation. Most efficient chemiluminescence reactions are thought to involveone or more electron transfer steps and chemiexcitation is believed to occurby radical annihilation. A brief introduction to the general principles of lightproduction and the main known chemiexcitation mechanisms will be given here.Subsequently, recent results on the mechanistic elucidation of efficient chemiluminescencesystems, as the peroxyoxalate reaction, the induced decomposition of phenoxy-substituted1,2-dioxetanes and the catalyzed decomposition of new a-peroxylactones willbe discussed.
