Synthesis and n-type semiconducting properties of soluble fullerene polymer particles

通过在富勒烯衍生物中引入长链烷基链的分子设计，合成了新型的可溶性富勒烯聚合物。在Prato条件下，富勒烯与含三个烷基的共聚单体共聚，得到了富勒烯含量为40wt%的超支化聚合物。电化学测量显示了多步还原波，表明保留了原始的富勒烯性质。对旋涂法制备的富勒烯聚合物薄膜的存储性能进行了评价。

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.
