英文摘要 | Anew pyrazolo[4,3-e]-1,3,4-oxadiazine heterocyclic ring system was prepared and employed to synthesize cyanine dyes of different methine types, including monomethine (simple cyanine) and trimethine (carbocyanine). The antibacterial activity of all the newly synthesized compounds was investigated against some bacterial strains. The electronic absorption spectra of the dyes were studied in absolute ethanol. The structure of all the synthesized compounds was identified via elemental and spectroscopic analysis. |
