FM/6-19110/A Charge-transfer complexes with N-aromatic compounds, the preparation thereof and the use thereof Abstract Charge-transfer complexes of formula I Image (I) wherein a) n is 1 or2, b) A is the radical anion of a compound of formula II or of a mixture of compounds of formula II Image (II) wherein the substituents R are the same and are H or C1-C4alkyl, or adjacent substituents R together form -(CH2)3- or -(CH2)4-; R1 is H or C1-C4alkyl; X1 is =N-CN; and X2, X3 and X4 are =O or =N-CN, and c) when n = 1, B is the monovalent radical cation and when n = 2, B is the divalent radical cation of an N-aromatic compound having a total of from 1 to 5 aromatic rings that are unsubstituted or substituted by halogen, C1-C4alkyl or by C1-C4alkoxy, at least one ring containing at least one group -NR2- or [=N+R2-] I wherein R2 is C1-C4alkyl or benzyl. The complexes are electrical conductors with which plastics materials may be anti- statically treated or converted into electrical conductors.
