Hybrid Conjugated Polymer–Inorganic Objects: Elaboration of Novel Organic Electronic Materials
Résumé
This chapter highlights recent developments in the elaboration of hybrid materials made of conjugated semiconducting polymers grafted onto various substrates such as metals, metal oxides, and carbon materials for organic electronic applications. The rapid development of multilayer architectures demands the preparation of well‐defined interfaces between both compatible and incompatible materials. Interface engineering is now known to help passivate charge trap states, control energy level alignments, enhance charge extraction, guide active layer morphologies, and improve material compatibility, adhesion, and device stability. Covalent bonds between materials are desired to yield intimate contacts and well‐defined interfaces. Following an overview of the various synthetic methodologies of conjugated polymers, the chemistry of tethering macromolecular chains onto nanoparticles and flat surfaces is described. The potential of these functional hybrid materials to deliver efficient and low‐cost devices in organic electronics is presented in the last section of this chapter.
