ω-dimethylaminoaldehydes were studied. Cross-conjugated ketones and meso-ethoxy(dialkylamino)tridecamethine salts containing the pyran or pyridone fragment were synthesized and their spectroscopicproperties were investigated. The replacement of the bridging O atom by the NMe group precludes an interaction between chromophores in cross-conjugated ketone and the related tridecamethine salt. In addition, the
研究了取代的4H-吡喃酮和N-甲基-2,6-二甲基吡啶酮与二甲基甲酰胺缩醛和共轭ω-二甲氨基醛的缩醛的反应。合成了包含吡喃或吡啶酮片段的交叉共轭酮和内消旋乙氧基(二烷基氨基)十三甲胺盐,并研究了它们的光谱特性。用 NMe 基团取代桥接 O 原子排除了交叉共轭酮中的生色团与相关的十三亚甲基盐之间的相互作用。此外,将内消旋氨基取代基插入含有中心吡喃鎓片段的盐的多甲炔链中会导致发色团相互作用的急剧减弱。尽管含有桥接 O 或 NMe 片段的酮菁的紫外光谱存在显着差异,
