Sažetak
Alkaline metal doping of C60 has been attracted much attention for its radical behaviour, [1] super conductivity, [2] and chemical reactivities.[3] Li endohedral fullerene (Li@C60) is, so to speak, ultimate 1 to 1 doping of C60. We reported synthesis and isolation of Li@C60 by electrochemical reduction of lithium-ion- encapsulated fullerene (Li+@C60) previously.[4] Its productivity was low (0.5–1 mg / 2–3 days) to investigate further research. For more productive method to synthesize Li@C60, chemical reduction was undertaken. The reaction of [Li+@C60]TFSI– and decamethylferrocene (FeCp*2) in dichloromethane gave brown precipitate. o-Dichlorobenzene solution of the solid showed NIR absorption corresponding to Li@C60. XRD pattern for the solid indicated similarity with azafullerene dimer (C59N)2, [5] which suggests the formation of (Li@C60)2 dimer in solid state. In this presentation, comparison with Li@C60 obtained from electrochemical reduction and ESR data will be discussed. [1] P. Rapta et al., ChemPhysChem 2002, 3, 351– 356. [2] P. W.
