Synthesis and characterization of fullerene derivatives with perfluoroalkyl groups

Abstract

Two novel C₆₀fullerene derivatives containing one or two perfluorooctyl groups were designed and efficiently synthesized. Organic field-effect transistors based on the bisperfluorooctyl compound 1 show high mobility up to 6.7 × 10⁻² cm² V⁻¹ s and high on/off ratio up to 5 × 10⁷, which qualifies compound 1 as promising n-type conductor material.
