| 摘 要： | 通过甲苯溶液中对─叔丁基─杯［８］芳烃与Ｃ６０的反应，合成了它们的１：１络合物．产物经红外光谱、元素分析、Ｘ－射线粉末衍射确证．还采用固体１３Ｃ核磁共振技术研究对─叔丁基─杯［８］芳烃对Ｃ６０的分子识别．１３Ｃ魔角固体核磁共振谱清楚地揭示出Ｃ６０被包结在杯芳烃的疏水空腔中．１３Ｃ核磁共振静态谱表明被包在空腔中的Ｃ６０分子于室温时仍在快速旋转．这说明Ｃ６０分子与对─叔丁基─杯［８］芳烃之间的相互作用非常弱．

| Abstract: | 1:1 inclusion complex has been synthesized by the reaction of p-tert -butyl-calix8]arene with C60 in toluene solution, and identified with infrared spectra, elemental analyses and X-ray powder diffraction. The molecular recognition of C60 by p-tert-butyl-calix 8] arene was studied by solid-state 13C NMR techniques.CP-MAS 13C NMR spectra disclosed unambiguously that C60 ball was encapsulated in hydrophobic cavity of p-tert-butyl-calix 8]arene. Wideline 13C NMR spectra indicated that C60 still rotated rapidly at room-temperature in the cavity of p-tert-butyl-calix-8]-arene. This implies that the interaction between C60 and p-tert-butyl-calix 8]arene is very weak. |
