PREPARATION OF RB3C60 UTILIZING ROOM-TEMPERATURE SOLUBILIZATION IN ALKYLAMINES

Alkylamines (n-propylamine and n-butylamine) Can be employed at room t emperature as solvents for the preparation of alkali-metal-intercalate d C-60 In this work, the preparation of Rb3C60 was studied in detail. The reaction produces a single phase as characterized by X-ray diffrac tion structural analysis. The product shows a superconducting transiti on at T-c similar to 28 K after thermal elimination of the amine. A st epwise mechanism of intercalation is proposed in which a fullerene-ami ne adduct forms first, followed by charge transfer between the adduct and Rb metal, followed by thermal decomposition of the adduct to yield Rb3C60.
