Abstract
Tractable doped electroactive polymers, comprising recurring units of a fused nitrogen-containing unsaturated heterocyclic ring system, are fabricated from the virgin polymer by contacting the polymer with donor or acceptor conductivity modifier atoms or groups of atoms.
Claims35
An electroactive polymer which comprises a charged polymer backbone of recurring diradical units of a fused 6,6 membered nitrogen-containing unsaturated heterocyclic ring system and charge compensating ionic dopants associated therewith wherein the polymer backbone is capable of undergoing a reversible oxidation or a reversible reduction or both to form said charged polymer backbone and said heterocyclic ring system contains at least two nitrogen atoms and none of said nitrogen atoms occupy the ring fusion position.
An electroactive polymer which comprises a charged polymer backbone and charge compensating ionic dopants associated therewith of the formula:
- ##STR44## wherein a is 0 or 1;
- b is 0 or 1;
- c is 0 or 1;
- n is an integer from 2 to 2,000;
- d is an integer from 1 to 40,000;
- s is an integer 1, 2, or 3;
- R is a fused six-member nitrogen-containing unsaturated diradical-heterocyclic ring system;
- R.sup.1 is the same as R or a different fused six-member unsaturated heterocyclic ring system;
- X is a connecting unit;
- Y is the same connecting unit as X or a different connecting unit;
- and M is a charge compensating ionic dopant of opposite electrical charge to the charge of the polymer backbone wherein the polymer backbone is capable of undergoing reversible oxidation or reversible reduction or both to form said charged polymer backbone.
