Substituted tetracyanoquinodimethanes, method for their preparation and their use as pi-acceptors and electrical semi-conductors

摘要

Compounds of the formula I (* CHEMICAL STRUCTURE *) in which R1 and R2 independently of one another are C1-C6alkyl, C3-C8cycloalkyl which is unsubstituted or substituted by C1-C4alkyl, or phenyl or benzyl which is unsubstituted or substituted by F, Cl, Br, C1-C6alkyl, C1-C6alkoxy or di(C1-C6alkyl)amino. The compounds are suitable as (pi)-acceptors and electrical semiconductors, and they can be used for antistatic finishing of objects.
