NEW MATERIAL: A biscyanoimine of formula I (where R1 is propyl, 5-20C alkyl, 3-20C alkenyl or I and each of R2-R4 is H, Cl, Br, I, F, phenyl, 1-20C alkyl, 3-20C alkenyl or 1-8C alkoxy).
EXAMPLE: 2-Dodecyl-N,N'-cyano-1,4-benzoquinonediimine.
USE: Starting material for a charge-transfer complex compound. This complex compd. and its radical ionic salt are used as an electric semiconductor and a photoconductor and are useful for the antistatic finishing of a synthetic resin and as an electrode of a cell, an electricity accumulating material, etc.
PROCESS: The compd. of the formula I is obtd. by allowing quinone of formula II to react with bistrimethylsilylcarbodiimide in an inert solvent in the presence of a catalyst such as TiCl4. The charge-transfer complex compd. is derived by allowing the compd. of the formula I to react with a fluvalene compd. in a specified molar ratio.
