title: Incarceration of Higher-Order Fullerenes within Cyclotriveratrylene-Based Hemicarcerands Allows Selective Isolation of C76, C78, and C84from a Commercial Fullerene Mixture.
abstract: Size-complementary 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 of C76/C78and C84in good purities (up to 95 and 88 %, respectively).
