Abstract

The fluorescence of 9-phenylxanthenium carbocation is efficiently quenched by aromatics, predominantly by a charge transfer mechanism in which the carbocation acts as an acceptor. The electron transfer nature of the quenching is established by laser flash photolytic observation of long-lived aromatic radical cations and 9-phenylxanthenyl radical in microsecond time regimes.
