抄録

2,6-Dialkylbenzo[1,2-b:4,5-b′]diselenophenes developed as soluble organic semiconductors gave a unique molecular arrangement in bulk single crystals, where π-stacking dimeric pairs and monomeric molecules are arranged in a similar manner to herringbone packing. Such unique structure was preserved in thin films on Si/SiO2 substrate, and the thin films fabricated by solution- or vapor-deposition acted as an active channel of field-effect transistors with mobility up to 8.4×10−2 cm2 V−1 s−1 for solution- and 2.3×10−1 cm2 V−1 s−1 for vapor-processed devices, respectively.
