2,6-Dialkylbenzo[1,2-2:4,5-b′]diselenophenes developed as soluble organic semiconductors gave a unique molecular arrangement in bulk single crystals, where π-stacking dimeric pairs and monorneric molecules are arranged in a similar manner to herringbone packing. Such unique structure was preserved in thin films on Si/SiO 2 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 cm -2 V -1 s -1 for solution- and 2.3 × 10 -1 cm -2V -1 s -1 for vapor-processed devices, respectively.
