A Search for New Ionic C60 Charge Transfer Complexes

Abstract
As one of the strategies to obtain ionic C60 charge transfer complexes, a doping of alkali metals to neutral CT complexes has been attempted under a mild condition. Superconductivity has been detected by magnetic measurements in OMTTF·C60·benzene doped with potassium or rubidium, where OMTTF is octamethylene-tetrathiafulvalene.
