Merocyanine dyes of the dihydropyridine series were prepared from salts of α(γ)-picolinium and cyanoacetic acid derivatives. Their spectral characteristics suggesting their structure in solution were studied. The change in the spectral properties depending on the substituents introduced into the structure of the substituents and solvents used (solvatochromism) was considered. The protonation of the dyes was studied, and its regioselectivity was established.
