For the synthesis of semiconducting metal containing polymers, polypyrrole main chain? It has the lowest conformational energy and is almost planar. The metal disulfide salt is formed by reacting with disulfide salt, which can be used as laser Q-switch material, optical disc recording medium, bar code material and superconductor.
