摘　　要：β－环糊精与环氧氯丙烷交联共聚物是一种具有三维网状结构的聚合树脂．它保留了β－环糊精所原有的与有机疏水基团形成包结物的特性．与一系列含有芳香环的有机显色剂配体（如吡啶偶氮染料、变色酸双偶氮试剂、三苯甲烷类碱性与酸性染料以及杂氧蒽酮类试剂等）均可形成相应的包结配合物．着重研究了有关包结配合物的稳定性及影响稳定性的各种因素．为进一步研究包结物分离富集痕量金属提供必要的理论依据．The cross linking polymer of β CD with epichlorohydrin is a polymerized resin containing 3 dimensional netted structure. It keeps the original character of β CD to form inclusion complexes with a series of organic reagents, such as pyridylazo,bisazochromotropic, triphenylmethane and xanthenone dyes etc. In this paper, the inclusive reactions of β CD polymer with above mentioned reagents, the stability constants and related thermodynamic parameters have been investigated. The reaction mechanism and the influence factor on the stability of inclusion compounds have also been discussed in detail.
