Abstract: Abstract A vinylogous series of anionic polymethine (cyanine) dyes has been synthesized based on tris(2,2,3,3,4,4,5,5-octafluoropentyl)-9 H -fluorene-2,4,7-trisulfonate. It has been found that their longest-wavelength and most intense electronic transition has the polymethinic origin, unlike the… read more here.
