LIQUID FULLERENE DERIVATIVE, METHOD FOR PRODUCING THE SAME, AND DEVICE USING THE SAME

摘要

Disclosed is a liquid fullerene derivative comprising a fullerene moiety, a benzene ring bonded to the fullerene moiety, and first to third alkyl substituents R₁, R₂ and R₃ respectively bonded at the 2-position, 4-position and 6-position of the benzene ring. Each of the first to third alkyl substituents R₁, R₂ and R₃ has at least 12 carbon atoms. This liquid fullerene derivative is in a liquid state at room temperature without requiring a solvent, and easily exhibits an intrinsic function of a fullerene. Also specifically disclosed are a method for producing such a liquid fullerene derivative and a device using such a liquid fullerene derivative.
