ResumoA flash-photolytic investigation was carried out on the hydrogen bonding interaction of triplet 2-naphthol and 1-anthrol with aromatic N-heterocycles such as 4-methylpyridine, quinoline, and benzo[h]quinoline. The deactivation of triplet 2-naphthol and 1-anthrol by aromatic N-heterocycles was found to be due to the hydrogen atom transfer reaction. The relationship between the reactivity and the reduction potential of aromatic N-heterocycles suggests that the electron transfer from the triplet to the quencher is the primary process of the hydrogen atom transfer reaction.
