| Abstract: | Novel mesoionic phenolates were synthesized via 4-hydroxyaryl-1,3-dithiolium salts and characterized spectroscopically by UV-Vis. The bathochromic effect induced by iodine substituents was investigated for several solvents. A negative solvatochromism was recorded for the intramolecular charge transfer absorption band.
