As a key part of future electronics, organic field-effect transistors (OFETs) have been attracted great attention owing to their advantages such as low cost, light-weight, mechanical flexibility, and solution processability. In order to compete with existing silicon technology, organic semiconducting materials need to enhance charge carrier mobility. Introduction of the flat molecular structure into the polymer backbones results in high charge carrier mobility in OFETs, because of increased intermolecular interaction by shortening the π-π stacking distance and intramolecular interaction by extended conjugation. Among the various flat molecules, quinoidal structure which connected with double bond between aromatic rings is suitable for obtaining co-planar conjugated polymers. In this presentation, we report new alternating copolymers based on a quinoidal moiety synthesized via Stille polymerization. Their thermal, optical and electrical properties are characterized and discussed. |
