Charge-transfer complex with N-aromatic compounds, their preparation and their use

摘要

Charge-transfer complexes of the formula I (A(-))nBn(+) (I), in which a) n is 1 or 2, b) A is the free radical anion of a compound of the formula II or a mixture of compounds of the formula II IMAGE in which the R are identical and represent H or C1-C4-alkyl, or the adjacent R together signify -(CH2)3- or -(CH2)4-; R1 denotes H or C1-C4-alkyl; and X1 signifies =N-CN and X2, X3 and X4 denote =O or =N-CN, and c) if n = 1, B is the monovalent free radical cation and if n = 2, B is the divalent free radical cation of an N-aromatic compound having in total 1 to 5 aromatic rings, which are unsubstituted or substituted by halogen, C1-C4-alkyl or C1-C4-alkoxy, at least one ring containing at least one group -NR2- or [=N+R2-] I-, in which R2 is C1-C4- alkyl or benzyl. The complexes are electrical conductors with which plastics can be antistatically finished or converted into electrical conductors.
