Summary
The 13C NMR of two solvatochromic dyes derived from a barbituric acid acceptor and dimethylaminophenyl donor fragments, compound 1 and the related merocyanine 2, were recorded in various solvents and the observed chemical-shift variations were used to interpret their structural differences and solvate behavior in solution.
