cyclotriveratrylene (CTV)‐based hosts can incarcerate C76, C78, and C84, thus allowing the selective isolation of these higher‐order fullerenes from a commercially available mixture of fullerenes. The hemicarceplexes, formed after the encapsulation of the size‐complementary fullerenes within the hosts, are isolated by column chromatography and released at elevated temperature, thereby leading to the isolation
基于尺寸互补的环三碳杂戊二烯(CTV)的宿主可以嵌顿C 76,C 78和C 84,因此可以从市售的富勒烯混合物中选择性分离这些更高阶的富勒烯。将大小互补的富勒烯包封在主体中后形成的半链状复合物,通过柱色谱法分离并在高温下释放,从而以良好的纯度(高达95%和95%的纯度)分离出C 76 / C 78和C 84。分别为88%)。
