Abstract
Solvatochromic studies on two new merocyanines, prepared from 5-(5-bromo-6-hydroxynaphthyl-2)-7,7-dimethyl-7H-indolo[1,2-a]quinolinium perchlorate and 5-(5-nitro-6-hydroxynaphthyl-2)-7,7-dimethyl-7H-indolo[1,2-a]quinolinium perchlorate, were performed in 21 solvents using UV–vis spectroscopy. The VBHB model (J.A. Soroka and K.B. Soroka in J. Phys. Org. Chem. 4:592–604, 1991) was applied to describe their solvatochromic properties.
