In order to find calix [n] arenes which can interact with [60] fullerene in solution we have screened a number of different calix [n] arenes by spectroscopic methods. We eventually discovered such three calix [n] arenes (p-tert-butylcalix [5] arene, p-tert-butylcalix [6] arene, and ptert-butylhomooxacalix [3] arene) which could accept [60] fullerene even in solution. They commonly possess a cone conformation and a benzene ring inclination suitable to [60] fullerene inclusion. Furthermore, it was found that calix [n] aryl ester derivatives, which cannot interact with [60] fullerene, become excellent [60] fullerene-acceptors in the presence of certain specific metal cations. This was attributed to a metal-induced conformational change to preorganeze cone calix [n] aryl esters. This phenomenon is a sort of positive allosterism, which is the first example in fullerene chemistry. We believe that these findings will open a door to new fullerene-calix [n] arene conjugate chemistry.

为了找到可以在溶液中与[60]富勒烯相互作用的杯[n]芳烃，我们通过光谱方法筛选了许多不同的杯[n]芳烃。我们最终发现了这三种杯[n]芳烃（对叔丁基杯[5]芳烃、对叔丁基杯[6]芳烃和对叔丁基高氧杂杯[3]芳烃）即使在溶液中也可以接受[60]富勒烯。它们通常具有适合[60]富勒烯包合的锥体构象和苯环倾斜度。此外，发现不能与[60]富勒烯相互作用的杯[n]芳基酯衍生物在某些特定金属阳离子存在下成为优异的[60]富勒烯受体。这归因于金属诱导的预有机锥杯[n]芳基酯的构象变化。这种现象是一种正变构现象，这是富勒烯化学中的第一个例子。我们相信这些发现将为新的富勒烯-杯[n]芳烃共轭化学打开一扇大门。
