Photoconductivity of 1,2-(1',2',2',2'-Tetracyanomethanoxymethano) [60] fullerene-Doped PVK

摘要

1,2-(1',1',2',2'-Tetracyanomethanoxymethano)[60] fullerene, a derivative of C_60, is a better electron acceptor than theparent C_60. The film of PVF 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 phtoinduced discharge curves and photoconduction spectra of the films were measured. The results showed that PVK doped with the C_60 derivative displayed more photoconductivity than that of PVK doped with pure C_60 or a mixture of C_60 and C_70.
