Claims2
TCNQ complex salts corresponding to the following general formula (I):
- ##STR13## wherein .gtoreq. n.gtoreq.0;
- R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, which may be the same or different, represent hydrogen, a straight- or branched-chain alkyl radical having from 1 to 30 carbon atoms or a cycloalkyl radical having from 5 to 12 carbon atoms with the proviso that R.sup.1 is not hydrogen;
- and X represents ##STR14## wherein R is defined as for R.sup.1.
TCNQ complex salts corresponding to formula (II):
- A.sup..sym. (TCNQ).sup..crclbar. (TCNQ).sub.n (II)
- wherein
- 2.gtoreq.n.gtoreq.0;
- and
- A.sup..sym. represents a cation corresponding to one of the following formulae ##STR15## wherein R and R.sup.1, which may be the same or different, represent a straight- or branched-chain alkyl radical having from 1 to 30 carbon atoms or a cycloalkyl radical having from 5 to 12 carbon atoms.
