✦ Synopsis

1,2-(1Ј,1Ј,2Ј,2Ј-Tetracyanomethanoxymethano) [60]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 .

Fullerene is irradiated in the presence of the electron transfer sensitizer 9,10dicyanoanthracene (DCA) under cosensitization with biphenyl. The generated radical cation C6o °+ reacts with H-donors such as tert-butylmethyl ether, propionaldehyde and alcohols to give 1:1-edduets, the 1-substituted 1,
