The main objective of the proposal is the synthesis of new one-dimensional Pd(III) nanowires constituted of a metallic core and of an organic shell. These wires are potential room-temperature superconductors. Two generations of wires can be identified. The first-generation wires display Pd(III)-Pd(III) bonds as a backbone and stabilizing conventional organic ligands: they are organometallic polymers and possess limited solubility and stability above -50°C. The second-generation wires also display Pd(III)-Pd(III) bonds as a backbone, but at least one stabilizing conventional ligand has been replaced by a polymer-functionalized ligand which will enhance both solubility and stability of the wires: they are organometallic copolymers. The possibility to access various morphologies with the new block copolymers should allow for targeting several applications, in fast digital circuits for example, as novel superconductors.
