Selective recognition and enrichment of C over C using an anthracene-based nanotube.

Selective recognition and enrichment of fullerenes (, C and C) remains challenging due to the same diameter and geometrical similarity. Herein, we report a hexagonal anthracene-based nanotube (1) through a one-pot Suzuki-Miyaura cross-coupling reaction. With anthracene-based side walls and pyridine linkers, 1 features a nano-scale tubular cavity measuring 1.
