The ATRP (atom‐transfer radical polymerization) process was used to synthesize C 60 end‐capped polystyrene. GPC data demonstrated that fullerene (C 60 ) was chemically bonded to polystyrene, and C 60 was most likely monosubstituted. Matrix‐assisted laser desorption/ionization‐time of flight (MALDI‐TOF) mass spectrometry (MS) analysis (with 1,8‐dihydroxy‐9(10H)‐anthracenone (dithranol)/silver trifluoroacetate as the matrix) of this copolymer proved that C 60 was monosubstituted.
