title: Head-to-tail and back-to-back dimerization of an open-cage fullerene derivative through π-π interaction-based self-assembly.
abstract: Open-cage fullerene derivative 2, C(59)(O)(4)(NAr)(2) (Ar = p-tBuC(6)H(4)), was prepared from 1, C(60)(O)(4)(OH)(2)(NAr)(2), through processes involving decarbonylation and elimination of the two hydroxyl groups. The phenyl groups in compound 2 act as chelating ligands for the fullerene cage and induce partial dimerization of 2 in solution. The single crystal X-ray structure of 2 shows strong intradimer π-π interactions and also weaker interdimer CH-π and π-π interactions.
