Abstract

A series of polyfluorinated triarylpyrazolines containing cationic piperazinium fragments in the fluorinated rings have been synthesized by substitution of para-fluorine atoms by 1-methylpiperazine and subsequent quaternization of the piperazine nitrogen atom. The relation between the structure of the obtained salts and their spectral characteristics has been studied, and photobleaching quantum yields in the presence of tetrabutylammonium butyl(triphenyl)borate have been measured.
