| Research Abstract |
Novel soluble fullerene polymers were synthesized by using the molecular design of introducing long alkyl chains into fullerene derivatives. Fullerenes were copolymerized with the comonomers bearing three alkyl chains under the Prato conditions, yielding the hyperbranched polymers with the fullerene content of >40wt%. Electrochemical measurements revealed multistep reduction waves, suggesting the retention of the pristine fullerene properties. The memory characteristics of the polymer thin films, prepared by spin coating the fullerene polymer solutions, were evaluated.
