摘要
采用分子复合的方法,在水溶液中合成了具有稳定结构的聚 N乙基4乙烯基吡啶/甲基橙复合物高分子染料。紫外可见吸收光谱发现得到的高分子染料在氯仿溶液中的吸收波长与染料单体在水溶液中的吸收波长相比发生了显著蓝移,其中最大可见吸收波长蓝移值达40 nm (由460 nm 到420 nm )。同时, D S C、 X射线衍射实验还研究了这种复合物的分子凝聚态结构。
A new polyelectrolyte complex dye was synthesized from poly N ethyl vinylpyridine cation and methyl orange anion in water. Obtained polycomplex is dissoluble in chloroform. UV spectra shows that the absorption waves of the complex in chloroform are great blue shift in comparison to methyl orange in water, the blue shift in visible region is about 40 nm(from 460 nm to 420 nm). The structure of the complex in solid state is also investigated by the DSC and X ray diffraction experiments.
