| Abstract: | A series of heterocyclic cyanine dyes were prepared. Unsymmetrical dyes showed self-micellizing properties due to the presence of two positive charges and of a long alkyl chain. Symmetrical dyes, containing three positive charges and not containing the hydrophobic chain, did not give rise to micelles. The physical properties of the dyes and their spectra were briefly discussed. Cationic (HTAB) and anionic (SDS) surfactants gave strong interactions with surface active dyes, leading to deaggregation and solvation phenomena. |
