使用可见光吸收光谱测量研究了含有两个季铵化氨基和两个苯环的芳香族 bolaform 电解质对磺化单偶氮染料和聚（乙烯基吡咯烷酮）之间相互作用的影响。由于芳香族 bolaform 电解质在较高浓度范围内聚集，因此在不形成聚集体的浓度范围内研究了染料和 bolaform 电解质之间复合物的形成。使用基于包含染料、bolaform电解质和聚(乙烯基吡咯烷酮)的三元系统中的平衡的方程来估计染料/bolaform电解质复合物与聚(乙烯基吡咯烷酮)的第一结合常数；这些值小于染料本身的值。通过使用根据第一结合常数的温度依赖性计算的热力学参数，与脂肪族 bolaform 电解质相比，讨论了芳香族 bolaform 电解质对染料和聚（乙烯基吡咯烷酮）之间相互作用的影响。
The effect of aromatic bolaform electrolytes which contain two quaternized amino groups and two phenyl rings on the interaction between sulphonated monoazo dyes and poly (vinylpyrrolidone) was investigated using visible absorption spectrum measurements. Since the aromatic bolaform electrolytes aggregated in a higher concentration range, the formation of complexes between the dyes and the bolaform electrolytes was investigated in the concentration range where no aggregate was formed. An equation based on the equilibria in the ternary systems containing the dyes, the bolaform electrolytes and poly (vinylpyrrolidone) was used to estimate the first binding constants of the dye/bolaform electrolyte complexes with poly (vinylpyrro-lidone); the values were smaller than those of the dyes themselves. The effect of the aromatic bolaform electrolytes on the interaction between the dyes and poly (vinylpyrrolidone) is discussed, as compared with that of aliphatic bolaform electrolytes, by using thermodynamic parameters calculated from the temperature dependence of the first binding constants.
