ABSTRACT:
The polymer material is made from a first monomer and from a second monomer. The first monomer Ar includes at least one aromatic nucleus and the second monomer is a five links conjugated heterocyclic ring. The polymer material has the following general chemical formula: ##STR1## in which: X represents the group constituted by sulphur and selenium; R.sub.1 and R.sub.2 are chosen from the group constituted by hydrogen, and by the alkyl, alkoxyl, and hydroxyl groups; and n is the degree of polymerization. Such materials can be made conductive by adding a doping agent, and they can then be used for manufacturing electrodes, junctions, Schottky barriers, etc.
