Covalent Binding of Fullerene С60 to Strained Polycyclic Hydrocarbons: Promising Organic Field-effect Transistors Based on them

Abstract: Hybrid molecules based on fullerene С60 and strained polycyclic hydrocarbons were synthesized for the first time using the Bingel–Hirsch reaction. The films of fullerene derivatives were deposited by centrifugation. The synthesized hybrid fullerene С60derivatives containing one strained polycyclic hydrocarbon moiety showed better charge carrier mobility than the fullerene derivatives containing two polycyclic hydrocarbon moieties. Apart from current–voltage characteristics, the morphology of the prepared hybrid compounds was studied. The best current– voltage characteristics were found for films with lower roughness. The fullerene С60 adducts containing strained polycyclic hydrocarbon moieties were used to fabricate organic field effect transistors (OFETs) with high-quality films; owing to this, the manufacturing process is compatible with modern printed organic electronics.
