Synthesis and UV/VIS spectroscopic properties of the negatively solvatochromic, chiral, (S,S)-configurated betaine dye 8 are described.There is a linear correlation between the E'T values of 8 and the ET(30) values of the standard betaine dye 1 (Figure 1).Unfortunately, (S,S)-8, dissolved in enantiomeric pure (R)- and (S)-configurated alcohols and amines, does not show a measurable chiro-sovatochromism (Table 2).
