Summary: The synthesis of star shaped poly( ε ‐caprolactone) (PCL) with a fullerene molecular core ( s ‐PCLF) was successfully achieved by the ring‐opening polymerization of ε ‐caprolactone with fullerenol as the initiator. Through NMR and GPC analysis, the average number of arms of PCL on each fullerene core was estimated to be 2–3.Fullerenol (left) and PCL star polymer (right) in THF.
