Abstract

1,2-(1′,1′,2′,2′-Tetracyanomethanoxymethano)[60]fullerene, a derivative of C60, is a better electron acceptor than the parent C60. The film of PVK doped with 1.6 wt % of this derivative was prepared and characterized. The micromorphology of the film was studied by transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM). The photoinduced discharge curves and photoconduction spectra of the films were measured. The results showed that PVK doped with the C60 derivative displayed more photoconductivity than that of PVK doped with pure C60 or a mixture of C60 and C70. © 1999 John Wiley & Sons, Inc.
