Novel monomethine, dimethine, trimethine and azastyryl cyanine dyes having 2-amino (methyl) benzimidazole were prepared. The electronic visible absorption spectra of all synthesized cyanines were investigated in 95 % ethanol to attempt and throw some light on the influence of such new heterocyclic nuclei and to compare spectral behavior. Antimicrobial activity of selected compounds against some bacterial strains was tested. Structural identification was carried out via elemental analysis, IR AND 1HNMR.
