摘要：

Conformational analysis of inclusion complexes of sodium 3-hydroxy-2-naphthalenecarboxylate with beta-cyclodextrin and heptakis-(2,3,6-tri-o-methyl)-beta-cyclodextrin in D2O was investigated by 1D and 2D (HNMR)-H-1 measurements. The results show that part of the naphthyl group of sodium 3-hydroxy-2-naphthalenecarboxylate is situated in the 2,3-OH side of the beta-cyclodextrin cavity asymmetrically while the whole naphthyl group is included in the heptakis-(2,3,6-tri-o-methyl)-beta-cyclodextrin cavity with the caboxylate and hydroxy group close to the 6-OCH3 group.
