摘　　要：研究了水溶性β-环糊精交联聚合物对含有双苯环的芳香席夫碱的荧光增强作用．发现除介质酸度外，双苯环客体间的距离是决定荧光增强程度的重要因素．当双苯环间隔3～4个原子时，分子发射荧光的能力明显增强．β-环糊精交联聚合物的这种特殊的立体选择性表明，其有可能成为一种新的分子荧光识别手段，并为β-环糊精交联聚合物应用于荧光增敏体系提供了理论基础．The enhancing fluorescence action of Schiff's bases containing double aromatic guests using water soluble β-cyclodextrin cross-linking polymer was studied in this paper.It was found that the distance between the two aromatic guests would be an important factor for enhancing fluorescence action. The ability of molecular fluorescence emission would be only enhanced when there was three or four atoms between two aromatic guests. This steric selectivity showed that the β-CD polymer would be possible to become a novel method for flourimetric molecular recognition of Schiff's bases containing double aromatic groups.
