A Neutral Mixed‐Valent Conducting Polymer Formed by Electron Transfer between Metal d and Ligand π Orbitals

Abstract

Frontier-orbital design aided in the preparation of the novel neutral linear chain rhodium(I,II) complex [Rh(3,6-dbdiox-4,5-Cl2)(CO)2]∞ (see picture), in which the mixed-valent state is formed by electron transfer between metal d and semiquinonate π* orbitals (3,6-dbdiox-4,5-Cl2: semiquinonate or catecholate of 3,6-di-tert-butyl-4,5-dichloro-1,2-benzoquinone). This compound exhibits high conductivity (17–34 S cm−1) at room temperature in spite of its being a neutral molecule.
