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
二氢吡啶系列的部花青染料由α(γ)-吡啶鎓和氰乙酸衍生物的盐制备。研究了它们的光谱特征,表明它们在溶液中的结构。光谱特性的变化取决于引入取代基结构中的取代基和所用溶剂(溶剂化变色)。研究了染料的质子化,并确定了其区域选择性。
