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

A novel naphthalene-based 5 center dot(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 center dot(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 center dot(BArF)8 displays distinct affinity for them.
