Abstract
Unsymmetrical polymethine dyes have been synthesized from 6-tert-butyl-4-methylthioflavylium perchlorates and nitrogen-containing heterocyclic aldehydes derived from julolidine and polyfluorinated triphenyl-4,5-dihydro-1H-pyrazoles. Spectral characteristics of the obtained compounds have been studied.
