Solvatochromism of mesoionic iodo(1,3-dithiol-2-ylium-4-yl)phenolates
摘要:
Novel mesoionic phenolates were synthesized via 4-hydroxyaryl-1,3-dithiolium salts and characterized spectroscopically by UV-Vis. The batho-chromic effect induced by iodine substituents was investigated for several solvents. A negative solvatochromism was recorded for the intramolecular charge transfer absorption band.
