Study on the Supramolecular Inclusion Complex of Fullerenes with p tert butyl Calixarene Benzyl Ether

Abstract

报道合成了一种新型的对叔丁基杯[8]芳烃苯醚,其在甲苯中可与球烯(C60、C70)形成超分子包合物.通过红外光谱、紫外光谱对所形成的包合物进行表征,探讨了影响反应的因素,测定了C60包合物的配合比为1∶1,而C70包合物的配合比为2∶1,它们的反应平衡常数kAS分别为1.810x103MOl-1·l和3.657x102(MOl-1·l)1/2,对包合物的构型进行了推测Two supramolecular inclusion complexes of fullerenes(C 60 and C 70 ) with a new type of calixarene(p tert butyl calixarene benzyl ether) was prepared.The inclusion complexes were characterized by UV Vis and IR spectrum.The stoichiometry ratio of C 60 inclusion complex is 2∶1 and that of C 70 inclusion complex is 1∶1.The association constants K ass of two inclusion complexes are 1.810×10 3 mol -1 ·L and 3.657×10 2( mol -1 ·L) 1/2 respectively.Their conformations were estimated.国家自然科学基
