    • note
    • A use of cationic sensitizers and chemically unreactive aromatic hydrocarbons so-called co-sensitizers is effective to observe radical cations in the LFP experiments. Under these conditions, a substrate radical cation is formed via electron transfer from a co-sensitizer to a photoexcited sensitizer followed by hole transfer from a co-sensitizer radical cation to a substrate
