文摘

Metallofullerene-containing copolymers (0.12, 0.20, 0.40, and 0.60 wt % Gd@C₈₂) were first synthesized via radical bulk copolymerization. The structures and the properties of the new polymers, Gd@C₈₂-PS, were investigated by GPC, UV−vis spectroscopy, FTIR, ¹³C NMR, CV/DPV, and XPS. The polymerization behavior of the metallofullerene and the properties of the Gd@C₈₂-PS polymers were different from those of C₆₀-PS and PS. Gd@C₈₂ exhibited a stronger radical-scavenging ability than that of hollow fullerenes in the polymerization. Molecular weights and the electron-accepting ability of the polymers were discussed and possible mechanisms of the influences were proposed.
