摘要：

The solvent dependence of the short-wavelength absorption bands of selected cyanine dyes incorporating 1H-pyrazolo[4,3-d]-[1,2,3]oxadiazole moiety was studied in the visible region. The spectra show a complex charge transfer CT transition and the assignments are based on solvatochromic behaviour of this transition. The absorption spectra in buffer solution have been also utilized to select the optimal pH value at which they can be applied as photosensitizers.
