摘要：
New asymmetrical pyrazolo [4,5-b] imidazo (3,2-a)/pyrolo (1,2-a) pyridinium/ quinolinium bromide 3[4(1)]-monomethine cyanines (Va-Vi); 3 [2(4)]-trimethine cyanines (VIIa-h) and/or 3-styryl cyanines (VIIIa-g) were synthesized to study their spectral behaviour, solvatochromism, mixed solvents and acid-base properties. These dyes are characterized by elemental analysis, IR, H-1 NMR, and electronic absorption spectra.
