Size-selective encapsulation of C60 and C60-derivatives within an adaptable naphthalene-based tetragonal prismatic supramolecular nanocapsule

Abstract

A novel naphthalene-based 5·(BArF) 8 capsule allows for the size-selective inclusion of C 60 from fullerene mixtures. Its size selectivity towards C 60 has been rationalized by its dynamic adaptability in solution that has been investigated by molecular dynamics. Additionally, 5·(BArF) 8 encapsulates C 60 -derivatives such as C 60 -PCBM and N-methylpyrrolidine-C 60 . The latter can be separated from C 60 since 5·(BArF) 8 displays distinct affinity for them.
