Abstract

Pentamethylidynecyanine dyes were synthesized by the reaction of 1-methyl-3-(R-phenyl)benzo[f]quinolinium quarternary salts with 1,3,3-triethoxy-1-propene, Pentamethylidynecyanines substituted in the meso position of the polymethine chain were obtained by condensation of these salts with 1-anilino-2-methyl-3-dimethoxy-1-propene hydrobromide. The spectral and generational characteristics of the dyes were determined. It was shown that the presence of a phenyl group in the benzo-[f]quinoline ring of the dyes gives rise to a bathochromic shift of the absorption and generation maxima. The investigated dyes have high generation efficiencies that lie in the 20–30% range and in the 940–1010 nm spectral range.
