The electrochemical behaviors of a novel class C 60 covalently linked PPV derivatives ( i.e., PPV‐1‐C 60 and PPV‐2‐C 60 ) in thin solid films as well as in solutions are reported. The first cathodic peak potentials of PPV‐1‐C 60 and PPV‐2‐C 60 have positive shifts by 30 and 50 mV, respectively, compared to pristine C 60 in formal cyclic voltammetry (CV). Simultaneous CV and piezoelectric microgravimetry of the drop‐coated thin solid films of PPV‐1‐C 60 and PPV‐2‐C 60 in acetonitrile solutions of TBA + counteractions are strongly influenced by the structure of the polymer‐C 60 , including the length of the chain macromolecule and the steric hindrance effect. In addition, the atomic force microscopy (AFM) images of PPV‐1‐C 60 and PPV‐2‐C 60 films deposited on Au/quartz electrode both exhibit even distribution. © 2002 Wiley Periodicals, Inc.
