摘　　要：在本工作中,我们测量了苯、甲苯及四氯化碳中:C_(60)和对叔丁基杯[8]芳烃及其混合液的紫外可见吸收光谱,C_(60)和对叔丁基杯[8]芳烃及其包合物的饱合溶解度,及包合物的浓度积;推算了上述有机溶液中C_(60)与对叔丁基杯[8]芳烃间包合反应的平衡常数及液相中真正以包合形式存在的包合物的溶解度;讨论了上述溶剂中包合物的存在形式、沉淀机理及溶剂效应.In this work, the UV - Vis absorption spectra of C60, tert-butylcalix [ 8 ] arene and their complex in benzene, toluene and carbon tetrachloride were studied. Their solubilities in these solvents were determined by the spectrophotometric evaluation. The concentration products of free C60 and tert - butylcalix [ 8 ] arene in the saturated solution of the complex were measured by a solution- precipitate equilibrium method. The true solubilities of the complex and the equilibrium constants of the inclusion reaction between C60 and tert - butylcalix[8]arene were estimated. The influence of solvent and the mechanism of precipitation were discussed.
