Electrogenerated Chemiluminescence: An Oxidative‐Reduction Type ECL Reaction Sequence Using Tripropyl Amine

A new electrogenerated chemiluminescence (ECL) reaction which utilizes tripropyl amine and is presented. The mechanism of light generation appears general enough to include a range of amines and luminophores. An oxidative‐reduction mechanism is proposed. Upon electrochemical oxidation of both the luminophore and amine, a strong emission is observed. Voltammetric analysis reveals the potential for greatest light emission at the tripropyl amine oxidation. The emission is from the excited state of . An electron transfer reaction from the deprotonated tripropyl amine radical and is the central reaction for excited state production. An estimate of the ECL efficiency cannot be made, due to the complex nature of the reaction.
