Synthesis, Absorption Spectra Studies and Antimicrobial Activity of Novel Monomethine, Dimethine, Trimethine and Azastyrylmethine Cyanine Dyes
Journal Title: International Journal of Science and Research (IJSR) - Year 2015, Vol 4, Issue 2
Abstract
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.
