摘要	Selective recognition and enrichment of fullerenes (e.g., C-60 and C-70) 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 1.2 nm in diameter and 0.9 nm in depth, along with pH-responsive properties. Interestingly, the electron-rich 1 shows high binding affinity (K-a approximate to 10(6) M-1) and selectivity (K-s approximate to 140) to C-70 over C-60 in toluene, resulting from their different contribution of pi-pi interactions with the host. The protonation of 1 simultaneously alters the electronic properties within the nanotube, resulting in the release of the fullerene guests. Lastly, the selective recognition and pH stimuli-responsive properties of the nanotube have been utilized to enrich C-70 from its low-content mixtures of fullerenes in chloroform.
