Dioxetane phenoxide substituted

The change of charge distribution during Ae reaction is important to clarify the intramolecular electronic process. In this paper we will focus on the change of HOMOs and the charge density distribution of unsubstituted 1,2-dioxetane (DO) and phenoxide substituted 1,2-dioxetane (PHOD) during the reaction. 

More than twenty years ago, Schaap et al discovered chemiluminescence from phenoxide substituted dioxetanes (PHOD) as a model for firefly bioluminescence. McCapra had suggested a charge or an electron transfer is involved for such process, but confirmative evidences had not been presented at that time. Recently successive synthetic efforts on phenoxide.substituted dioxetanes produced a series of efficient chemiluminescent molecules. ...
