Abstract: Nerv asymmetrical naphtho/quinolinoquinone[2,3-d]thiazole/oxazole-4,9-dione 2[4(1)]-monomethine cyanines and naphthoquinone[2,3-e]oxadiazine-5,10-dione 2[4(1)]-monomethine cyanine dyes were synthesized to study their spectral behaviour, solvatochromism, acid-base properties, and antimicrobial activities. This study discloses the activity of former quinoid ring in cyanine dyes when applied as photosensitizer. These dyes are characterized by elemental analysis, IR, ¹H NMR, and electronic absorption spectra.
