摘　　要：本文用荧光光谱法研究了α-溴代萘(α-BrNp)在β-环糊精(β-CD)水溶液中与β-CD的相互作用.实验结果表明这一相互作用所引起的体系的荧光光谱的变化反映了两个1:1的α-BrNp-β-CD包络物分子可以在一定的条件下进一步形成一种2:2的重叠包络物.The interaction between a - bromonaphthalene and (3 - cyclodextrin in aqueous solution have been studied by fluorimetry. The experimental results show that there is a new kind of inclusion complexes - 2 : 2 overlapping inclusion complex which consisted of two 1 :1 inclusion complexes has been formed, the direct evidence is the change of the fluorescence spectra.
