REGENERATIVE MECHANISM OF ACTIVATION OF CHEMILUMINESCENCE FROM THE REACTION OF DIETHOXYETHYLALUMINUM WITH XENON DIFLUORIDE

The influence of emission activators-9,10-dibromoanthracene; pyrene; p -terphenyl; and [Ru(bipy)(3)Cl-2.(OAC)(n)] complex, where OAC denotes an organoaluminum compound-on chemiluminescence from the reaction of d iethoxyethylaluminum (EtO)(2)AlEt with xenon difluoride in solution wa s studied. Luminescence enhancement was shown to be due to activator p articipation in oxidation-reduction processes rather than energy trans fer from the primary emitter to an excitation level of the activator. Excitation of an activator molecule or the Ru(2+) complex was found to occur when the oxidized form of the activator is reduced by the initi al organoaluminum compound, for example: Ru(3+) + OAC --> Ru(2+)+ OAC (.+).
