Complex formation of pyromellitic diimide derivatives with beta-cyclodextrin and anthracene-appended beta-cyclodextrin was studied with use of induced circular dichroism and 1H NMR spectroscopies. It is revealed that pyromellitic diimides form rim-binding type complexes with beta-CD and in these complexes the pyromellitic diimides lie just outside of the narrow rim of the CD. With anthracene-appended beta-CD the pyromellitic diimides form true inclusion complexes. Implications of the formation of rim-binding type complexes are also discussed.
利用诱导圆二色光谱和1H核磁共振光谱研究了均苯四甲酸二酰亚胺衍生物与β-环糊精及蒽基化β-环糊精的络合物形成情况。结果表明，均苯四甲酸二酰亚胺与β-环糊精形成边缘结合型络合物，在这些络合物中，均苯四甲酸二酰亚胺位于环糊精窄边缘的外侧。均苯四甲酸二酰亚胺与蒽基化β-环糊精形成真正的包合物。还讨论了边缘结合型络合物形成的意义。
