Pyridinium N-Phenoxide Betaines and Their Application for the Characterization of Solvent Polarities, XVIII. - Synthesis and UV/Vis Spectroscopic Properties of a Negatively Solvatochromic Pyridinium N-Thiophenoxide Betaine Dye
Reichardt, Christian,Eschner, Michael
, p. 1003 - 1012 (2007/10/02)
Synthesis and UV/Vis spectroscopic properties of the negatively solvatochromic, relative to 1 homomorphic, thiobetaine dye 2 are described.The new thiobetaine 2 exhibits an even larger negative solvatichromism and thermochromism than the standard betaine
