利用平衡键合模型模拟了聚电解质同荧光探针离子键合过程的计量关系 ,以及添加盐竞争键合时的计量关系 .计算的结果能够描述荧光实验结果 .芘离子探针PyMeA·HCl的IE IM 随着探针浓度的增加 ,会出现一个极大值 ,此极大值能够定量地给出饱和键合计量关系 .当盐浓度和聚电解质荷电单元浓度相当时 ,盐离子和芘离子探针发生明显的竞争键合 ,部分离子探针被排挤入水相 ,实验的IE IM 随盐浓度增大急剧减小 The equilibrium binding model was used to simulate the relationship between the polyelectrolytes and the fluorescence probe ion bonding process and the binding relationship of the added salt in the competitive bonding. The calculated results can describe the fluorescence experiment results. Pyrene ion probe PyMeA · HCl IE IM As the probe concentration increases, a maximum appears, which gives a quantitative measure of the saturation bond. When the salt concentration is comparable to that of the polyelectrolyte charge cell, salt ions and pyrene ions A significant competitive bonding took place between the needles and some of the ion probes were forced into the aqueous phase. The experimental IE IM sharply decreased with increasing salt concentration
