摘　　要：采用单扫描极谱法考察了 β 环糊精对 15种不同结构类型的碱性染料在不同支持电解质中电化学性质的影响 ;用“电流法”测定了包结常数 ;比较了不同主客体分子之间的包结作用 ,探讨了包结物在形成过程中的多种影响因素。结果表明 ,碱性染料环糊精包结物的形成受支持电解质 ,染料分子的结构类型及亲水性等多种因素的制约 ,而体积相适为包结作用的决定性因素。The effect of β-cyclodextrin (β-CD) on the electrochemical properties of 15 different structural basic dyes in different supporting electrolytes was studied by the single-sweep polarography;The inclusion constants of basic dyes with β-CD were determined based on “electric current method”. The inclusion interactions of subject molecule with different guest molecules were compared. The influence of various factors on the forming process of the inclusion complexes was discussed. The results show that formation of inclusion complexes is restricted by various factors,such as supporting electrolytes,the structure of dyes,the function of hydrophilic etc.,and the matching of volumn is the decisive factor.
