Bis(2-acenyl)acetylene compounds that are useful as organic semiconductors are disclosed. The compounds, when used as the active layer in OTFTs exhibit device characteristics, like charge-carrier mobilities and current on/off ratios, that are comparable to those of pentacene. Also described are semiconductor devices comprising at least one compound of the invention; and articles comprising the semiconductor devices such as thin film transistors or transistor arrays, and electroluminescent lamps.
本发明揭示了作为有机半导体有用的双(2-
芴基)
乙炔化合物。当这些化合物作为OTFTs中的活性层时,表现出与五环
芴相当的器件特性,如载流子迁移率和开关比。还描述了包括本发明至少一种化合物的半导体器件;以及包括半导体器件的物品,如薄膜晶体管或晶体管阵列,以及电致发光灯。
