Abstract
2-[4-(2,4,6-Triarylpyridinium-1-yl)phenyl]indan-1,3-dion-2-ides 5a–d, (N+C-) betaine dyes, were synthesised by reaction of 2,4,6-triarylpyrylium perchlorates 6a–d with 2-(4-aminophenyl)indan-1,3-dione 7. The solvatochromic effect of compounds 5 was investigated. The betaines obtained are suitable for polarity determination of carboxylic acids and their anhydrides.
