Outline of Final Research Achievements

Recently, high-mobility organic field-effect transistors (OFETs) based on new pi-conjugated molecules and polymers attract significant attention. In this study, we have employed electron spin resonance (ESR) spectroscopy in detecting the charge carriers with spins in OFETs to elucidate their dynamics and electronic states. ESR parameters such as g-values have been theoretically analyzed using density-functional (DFT) calculations. As a result, significantly small activation energy of ~10meV has been revealed in an alkylated small molecule with extended pi-core (C10-DNTT). In the case of typical semicrystalline polymer, PBTTT, high-density reversible doping using ionic-liquid-gated transistor structures has clearly indicated the change of electronic states from polarons with spins via spinless bipolarons to the onset of metallic state. These results demonstrate the high potential of high-mobility materials for device applications as well as for the development of new functionalities.
