Chemically Initiated Electron Exchange Luminescence. A New Chemiluminescent Reaction Path for Organic Peroxides.
Abstract
The thermal decomposition of diphenoylperoxide in the presence of certain aromatic hydrocarbons generates benzocoumarin and light corresponding to the fluorescence spectrum of the hydrocarbon. It is shown that this chemiluminescence does not result from conventional energy transfer from some electronically excited peroxide decomposition product to the aromatic hydrocarbon. Instead, the chemiluminescence is initiated by electron transfer from the hydrocarbon to the peroxide followed by rapid decarboxylation and back electron transfer to form the electronically excited hydrocarbon. The yield of light from this process is quite high. It is suggested that a similar mechanism may be operating in several previously described chemiluminescing systems. (Author)
