Solvent-vapor-annealed A–D–A-type semicrystalline Conjugated Small Molecules for Flexible Ambipolar Field-effect Transistors |
| 초록 |
This paper reports a series of A–D–A type small based on an oligothiophene–phenylene core with three different electron-accepting terminal groups—VCN, RCN, and INCN, respectively—for application to flexible ambipolar OFETs. All the P3T4-based OFETs exhibited ambipolar behavior with hole-dominant transport, and the OFET performances were strongly dependent on the terminal groups. The P3T4-INCN OFET exhibited the highest carrier mobility owing to the extended π-conjugation via the INCN moiety, which enhanced the intermolecular cofacial π–π stacking and generated an efficient carrier pathway in the transistor channel. Room temperature solvent vapor annealing resulted in a dramatic increase in the carrier mobility of the OFETs without causing any damage to a PEN substrate. |
