运用聚甲基丙烯酸二甲胺基乙酯(PDMAE)的季胺盐(PDMAEB)在水溶液中与酸性金黄(MY)进行了组装,并制得相应的组装产物。傅立叶红外光谱表明复合物的确是通过静电作用复合形成的,未生成新的化学键。荧光发射光谱表明复合物乙醇溶液的荧光发射较酸性金黄乙醇溶液的荧光发射发生了蓝移。同时,DSC、X射线衍射实验还研究了这种复合物分子的凝聚态结构。
A new polyelectrolyte complex was synthesized from quaternary salt of poly(N,N-dimethyamino ethyl methacrylate)(PDMAEB) and metanil yellow(MY) in water. FT-IR spectra shows that the assembly is formed chiefly through electrostatic interaction between PDMAEB and MY without new bonds emerging. The fluorescence spectra shows that the emission waves of the complex in ethyl alcohol are blue- shift in comparison to MY in ethyl alcohol. The structure of the complex in solid state was also investigated by the DSC and X-ray diffraction experiments.
