α,ω-Dihexylthienoselenophene derivatives: a new class of high-performance semiconductors for organic thin-film transistors

Abstract

α,ω-Dihexylthienoselenophenes (Se2Thx) are readily prepared oligomeric species that can be used as the semiconducting layer in organic thin film transistors (TFTs). These selenophene-containing oligomers exhibit high hole mobilities (0.023 and 0.16 cm2 V−1 s−1) and good on/off ratio (105–106) that are improved relative to their sulfur-containing counterparts. X-Ray diffraction measurements and atomic force microscopy give insight into the internal structure and surface topography of the materials.
