Metallic Polymers Mediated by Ions, and Interstices

Abstract

Chemical doping of polymeric semiconductors involves the electron transfer between the host polymer and guest dopant, representing a host-guest binary system. The successful introduction of functional dopant molecules or ions into an interstice of crystalline polymers improves the doping level. A metallic state with degenerated, coherent electrons is realized particularly via anion exchange doping. The resulting high doping level and enhanced conductivity could allow an in-depth understanding of electronic states in polymeric semiconductors, and may possibly open up opportunities for exploring novel functionalities of conductive polymers.
