A novel charge transfer complex of an N,N'-biscyanoquinone bisimine of the formula ##STR1## and a fulvalene derivative of the formula ##STR2## where, in formula I, R.sup.1, R.sup.2, R.sup.3 and R.sup.4 independently of one another are --H, --CH.sub.3, --C.sub.2 H.sub.5, --OCH.sub.3, --OC.sub.2 H.sub.5, --Cl and/or --Br, and one of the radicals R.sup.1 and R.sup.2 and/or one of the radicals R.sup.3 and R.sup.4 may furthermore be phenyl or tert.-butyl, or R.sup.1 and R.sup.2 and/or R.sup.3 and R.sup.4 together form ##STR3## and the fused-on aromatic ring is unsubstituted or substituted, and, in formula (II), R.sup.5, R.sup.6, R.sup.7 and R.sup.8 independently of one another are each --H, --CH.sub.3, --C.sub.2 H.sub.5, phenyl, methylphenyl or methoxyphenyl, or R.sup.5 and R.sup.6 and/or R.sup.7 and R.sup.8 together form ##STR4## where n=3, 4 or 5, ##STR5## and X and Y indendently of one another are each S or Se. In the crystalline state, the charge transfer complex possesses electrical conductivity and accordingly can be used as an electrical semiconductor or photoconductor. Novel biscyanoquinone imines of the formula (I), where R.sup.1, R.sup.2, R.sup.3 and R.sup.4 have the stated meanings, and a novel process for the preparation of the compounds (I).
