The effect of the addition of alcohols on the photoinduced electron transfer reaction of a naphthalene-triethylamine system has been studied.The result show that the addition of alcohol reduces both bimolecular rate constants for the quenching of the naphthalene fluorescence by triethyamine and the quantum yields for the formation of products, in the order of 2-methyl-2-propanol <2-propanol < ethanol < methanol.These results are explained in terms of a hydrogen-bonding interactions between the amine and alcohols, which suppress the electron transfer process.
