Poly(furfuryl isocyanate) (PFIC), which includes the reactive furan group, was synthesized by anionic polymerization using a sodium benzhydroxide (Na‐BH), self‐assembly initiator. We determined the optimum polymerization conditions by varying both the reaction time and the molar ratio of the monomer to the initiator. Block copolymer, poly(furfuryl isocyanate)‐b‐poly(n‐hexyl isocyanate), was synthesized under optimized polymerization conditions. The PFIC was modified by Diels–Alder reactions with C60 for functionalization. Transmission electron microscopy (TEM) was used to study the self‐assembly of block copolymers and modified block copolymer with C60. C60 formed highly ordered aggregates on the PFIC domains via self‐assembly of the block copolymer.
