Abstract: New asymmetrical pyrazolio[4',5':4,5]imidazo[3,2-a]/pyrrolo[1,2-a]pyridinium/quinolinium bromide iodide 1[4(1)]-monomethine cyanines: 1[2(4)]-trimethine cyanines and/or 1-styryl cyanines were synthesized to study their spectral behaviour, solvatochromism, mixed solvents, and acid-base properties.These dyes are characterized by elemental analysis, IR, ¹H  NMR, and electronic absorption spectra.
