Photoconductivity of 1,2-(1 ',1 ',2 ',2 '-tetracyanomethanoxymethano)fullerene-doped PVK
1,2-(1',1',2',2'-Tetracyanomethanoxymethano)fullerene, a derivative of C-60, is a better electron acceptor than the parent C-60. 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 C-60 derivative displayed more photoconductivity than that of PVK doped with pure C-60 or a mixture of C-60 and C-70.
