    Abstract

    Fluorescence quenching of an amphiphilic intercalator (an electron donor, C18AO+) by an amphiphilic viologen (an electron acceptor, C12BhPC5V2+) in a cationic monolayer of 2C18N+2C1 was enhanced when the monolayer formed polyion complexes with double-stranded polynucleotides at the air-water interface. Fluorescence intensity and quenching efficiency were strongly depended on structure of polynucleotides.
