Solvation of some α-N,N-dimethylaminostyryl-N-alkyl pyridinium dyes has been studied in binary solvent mixtures of alcohol–hexane, alcohol–1,4-dioxane, acetone–hexane, acetone–1,4-dioxane, DCM–hexane, DCM–1,4-dioxane and 1,4-dioxane–hexane to analyze the preferential solvation of any of the solvent in the binary mixture. Due to solvent–solvent interaction, hyper and hypo-polarity in the solvent complex
已经研究了一些α-N,N-N-二甲基氨基苯乙烯基-N-烷基吡啶鎓染料在醇-己烷,醇-1,4-二恶烷,丙酮-己烷,丙酮–1,4-二恶烷,DCM-己烷,DCM–1,4-二恶烷和1,4-二恶烷–己烷分析二元混合物中任何溶剂的优先溶剂化。由于溶剂之间的相互作用,在溶剂配合物中观察到了超极性和低极性,这从染料分子的吸收最大值的红移和蓝移反映出来。染料周围的溶剂笼受到极性-极性和非极性-非极性相互作用以及两种相互作用类型之间适当平衡的影响。
