Aqueous electrochemiluminescence of polycyclic aromatic hydrocarbons immobilized into Langmuir–Blodgett film at the electrode

In this paper the aqueous electrochemiluminescence (ECL) from polymethylmethacrylate Langmuir–Blodgett films incorporating water insoluble luminophors as rubrene (RUB) and 9,10-diphenylanthracene (DPA) at the electrode was obtained. ECL was excited using reaction with coreactant tripropylamine in aqueous solution in the anodic potential range using scanning voltammetry method. Dependence of ECL response of RUB films versus their thickness and coreactant concentration was also studied.
