Abstract

We report on electron transporting organic transistors and integrated ring oscillators based on four different solution processible fluorine containing C60 derivatives. Electron mobilities up to 0.15 cm2 V s are obtained from as-prepared bottom-gate, bottom-contact transistors utilizing gold source-drain electrodes. Despite the high mobility, no long-range structural order could be identified with the semiconductor films exhibiting amorphouslike characteristics. The good electron transport is attributed to the structural symmetry of the fullerene derivatives and the enhanced π -π interactions between C60 units even in the case of amorphouslike films. These advantageous characteristics make fluorine containing C60 derivatives attractive for application in high-performance, large-area organic electronics.
