苯衍生物（苯、苯酚、乙氧基苯、苯胺、N-甲基苯胺、N。N-二甲基苯胺和N-二乙基苯胺）与β-环糊精在水溶液中形成包合络合物。用吸收光谱法和荧光光谱法测定了这些包合物的平衡常数。荧光增强后，观察到所有苯衍生物的研究。其中，苯胺和N-甲基苯胺表现出明显的包结作用。这些结果进行了讨论的基础上，周围的环境变化的荧光分子时列入。
Benzene derivatives (benzene, phenol, ethoxybenzene, aniline, N-methylaniline, N. iV-dimethylaniline, and IV^ V-diethylaniline) form inclusion complexes with (3-cyclodextrin in aqueous solutions. The equilibrium constants of these inclusion complexes were obtained by absorption and/or fluorescence spectrophotometric methods. Fluorescence enhancement was observed upon inclusionfor all benzene derivatives studied. Of the compounds, aniline and N-methylaniline showed marked effects of inclusion. These results are discussed on the basis of environmental changes around fluorescent molecules upon inclusion.
