Intrinsically conductive doped polymers of enhanced stability

Abstract

Abstract This invention relates to the discovery of a novel class of intrinsically electrically conductive doped solid organic homopolymers having a conductivity when measured by the four point probe method at standard temperature conditions within the range of about 10 -3 to 10 ohms -1 cm -1 developed by either treatment of the organic polymer surface with an electron donor or an electron acceptor dopant. The individual "mer" unit of the useful polymeric class of homopolymers for the purposes of accepting the dopant treatment consist of homopolymers having the repeating general structure: ##STR1## wherein the useful members of this class require that the R 1 and R 2 substituents in the illustrated structured "mer" are not both hydrogen substituents. However, in many instances of individual operative members of the class R 1 and R 2 may be otherwise a halogen or moities of a simple hydrocarbon structure, particularly methyl, when alkyl group extended chains, such as isopropyl, have been equated by theoretical comparison, likewise, it is also established that the simple phenyl (aromatic) group is also functionally useful. The "mer" units of the polymer are isolated which is in contrast with prior art polymers which have been suggested or useful which contain conjugated bond structures.
