Notes:
The halochromism of the negatively solvatochromic pyridinium N-phenoxide betaine dye 1 has been measured in acetonitrile solution and linearly correlated with the effective charge of the cations of the added alkaline and alkaline earth salts. The observed negative halochromism of betaine dye 1 constitutes a new type of true halochromism, in contrast to the trivial halochromism found for the first time by Baeyer and Villiger in 1902.
