Effect of Concentration on Isomerization of Rhodanine Derivatives of Merocyanine Dyes in Polar Solvents

Figure 8

Effect of protonation on electronic absorption spectra of (a) 1a and (b) 2a in DMF: (1)—no acid; (2)—HCl added, molar ratio of acid to dye was 10 : 1. Dye concentration was 10−5 M in all cases.
