摘　　要：用紫外可见吸收光谱和荧光光谱表征了5-NO2-SA与β-CD分子间的相互作用,讨论了取代基对包合作用的影响。结果表明β-CD对5-NO2-SA有一定的包合作用,包合常数为Kf=35.03±0.18mol-1·L。The interaction between β-cyclodextrin with 5-nitrosalicylic acid was studied by UV-Vis and fluorescence.β-cyclodextrin can conclude 5-nitrosalicylic acid.The β-cyclodextrin and 5-nitrosalicylic acid form 1∶1 inclusion.The conclusion constant was calculated and the effects of substitution to the conclusion was discussed.
