摘要：
Size-complementary cyclotriveratrylene (CTV)-based hosts can incarcerate C-76, C-78, and C-84, 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 of C-76/C-78 and C-84 in good purities (up to 95 and 88%, respectively).
