球烯与对叔丁基杯[8]芳烃苯醚形成超分子包合物的研究

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

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１．８１０×１０３ｍｏｌ－１·Ｌ和３．６５７×１０２（ｍｏｌ－１·Ｌ）１／２。

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.
