โœฆ Synopsis


The application of Marcus theory of electron transfer reactions f&r the use cf radical ion chemiluminescence of 9,10diphenylanthracene (DPA) gives a high rate constant value (LOY -10" M-' S-'1 for the formation of the second triplet state CT*). It is suggested that the near infrared emission observed during electrochemiluminescence of DPA is due to T2 -+ T'l fluorescence based on the high yield of T2 (=0.7) in the electron transfer readtion.

Electron transfer from the triplet excited state of N,N,N',N'-tetramethylphenylene diamine to phthalic anhydride has been monitored by phosphorescence emission decay. The kmetics of the transfer process were observed directly and the rate constant depends exponentially on the reacting distance, k(r)
