摘要:
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 pi-pi interactions and also weaker interdimer CH-pi and pi-pi interactions.
