Abstract

Films of an oxygen-linked fullerene polymer were synthesized by exposing about 15-nm-thick fullerite layers to ozone at room temperature. Moderate ozone exposure was found to lead to a polyoxifulleride that was stable in a vacuum up to at least 800 K. The oxidation and polymerization process was monitored by corelevel and valence-band photoelectron spectroscopy, which suggested that the bonding between fullerenes was by furan-like oxygen bridges and that the resulting polymer was three-dimensionally linked. The redox potential of the film was unaffected by this kind of polymerization, as witnessed by the unimpaired fullereneinduced surface conductivity of diamond. Hence, in addition to stabilization of the diamond surface conductivity, the polymerization is expected to be of considerable importance for C60-based bulk heterojunction organic solar cells, as well as for C60-based field-effect transistors. Similar albeit less effective thermal stabilization was also achieved for the fluorofullerene C60F48. © 2010 American Chemical Society.
