摘要

11,11,12,12-Tetracyano-9,10-anthraquinodimethane compounds useful as semiconductors and which have the general formula (I) …CHEM… in which Z1, Z4, Z5 and Z8 independently represent hydrogen, chlorine, hydroxy or amino and Z2, Z3, Z6 and Z7 independently represent hydrogen, halogen, alkyl which has 1 to 8 carbon atoms, phenyl, alkylphenyl whose alkyl group has 1 or 2 carbon atoms, hydroxyalkyl which has 1 to 8 carbon atoms, carboxyalkyl whose alkyl group has 1 to 8 carbon atoms, hydroxy, amino, or carboxyl, are prepared by introducing dicyanomethyl groups into an anthracene compound of the general formula (II) at the 9- and 10-positions …CHEM… in which Z1 to Z8 have the same meaning as above, and dehydrogenating the dicyanomethyl groups.
