  Abstract:  The synthesis of new 2-(2-(3-formyl-10H-phenothiazin-7yl)vinyl)-3H-indolium iodide and comparison of the UV–visible absorption/ emission spectral changes for several indolium cyanine dyes upon variation of organic solvents and aqueous solutions with pH in the range between 5–8 pH units were described.

Keywords: cyanine dyes, phenothiazine, indolium iodide, solvatochromism, pH sensitivity
