环糊精胺衍生物-Cu^(2+)-苯甲酸三元配合物的园二色性研究

STUDY OF THE CIRCULAR DICHROISM FOR TRIBASIC COMPLEX OF AMINE DERIVATIVE OF βCYCLODEXTRINDIENCu2+BENZOIC ACID

用ＪＡＳＣＯＪ－２０Ｃ自动记录旋光仪测定了β－ｃｙｃｌｏｄｅｘｔｒｉｎｄｉｅｎ，β－ｃｙｃｌｏｄｅｘｔｒｉｎｄｉｅｎ－Ｃｕ２＋配合物，β－ｃｙｃｌｏｄｅｘｔｒｉｎｄｉｅｎ－苯甲酸配合物及β－ｃｙｃｌｏｄｅｘｔｒｉｎｄｉｅｎ－Ｃｕ２＋－苯甲酸三元配合物的园二色谱，并利用Ｃｕ２＋配合物及苯甲酸的轨道能级顺序对谱带进行了归属。并根据Ｃｕ２＋配合物的结构特征及ＫＡＪＡＲＴ扇形规则确定了配合物的结构。

The circular dichroism spectra of βcyclodextrindien,βcyclodextrindienCu2+complex,βcyclodextrindienbenzoic acid complex,tribasic complex of βcyclodextrindienCu2+benzoic acid were determined by using JASCO J20C automatic recording spectropolarimeter.The attribution of the bands obtained were made according to the order of orbit energy of Cu2+ complex and benzoic acid,and the coordination structure of tribasic complex of amine derivative of βcyclodextrindienCu2+benzoic acid were decided acording to the structure character of Cu2+ complex and KAJART sector rule of inclusion complex of βcyclodextrindien with aromatic compounds.
