抄録

A novel and versatile method to align polymer semiconductors is demonstrated. Spreading and subsequent mechanical compression of a polymer thin film on an ionic liquid's surface yield a polymer thin film that has high uniaxial orientation of the polymer backbone, which is tested for typical polymer semiconductors of PB16TTT, PNDTBTC20, and P3HT. TFTs fabricated by the method exhibit significantly higher mobility compared to TFTs fabricated using a conventional spin-coating process.
