Facile Purification of C60O-Containing [60]Fullerene Using Trialkylphosphines at Room Temperature
A novel method using trialkylphosphines is reported for the facile purification of [60]fullerene containing C60O. When tri-n-butylphosphine and tri-n-octylphosphine were added to unrefined C60 (ca. 97% purity) in 1,2,4-trimethylbenzene, C60O was readily reduced to give high-purity C60 (>99% purit...

Zusammenfassung: | A novel method using trialkylphosphines is reported for the facile purification of [60]fullerene containing C60O. When tri-n-butylphosphine and tri-n-octylphosphine were added to unrefined C60 (ca. 97% purity) in 1,2,4-trimethylbenzene, C60O was readily reduced to give high-purity C60 (>99% purity). The best results were obtained for a high concentration (>1.0 wt %) of unrefined fullerene treated with tri-n-octylphosphine at room temperature. This method is simple and fast in comparison with conventional alumina chromatography, and thus, it is well-suited to industrial-scale separation. |
