Abstract
A new series of benzimidocarbocyanine dyes having diffeerent N-alkyl chain lengths (C2−C12) but the same chromophoric system was synthesized to investigate the effect of the dye structure on the photophysical properties of J-aggregate-forming dyes. For these dyes, the number of J-absorption band depends on the chain length of the alkyl substiuents, whereas the fluorescence emission spectra exhibit only a single J-band. Furthermore, an increase in the N-alkyl-chain length leads to a strong decrease in the bandwidth of the J-absorption and emission bands.
