2,7-Dialkyl[1]benzothieno[3,2-b]benzothiophenes were tested as solution-processible molecular semiconductors. Thin films of the organic semiconductors deposited on Si/SiO2 substrates by spin coating have well-ordered structures as confirmed by XRD analysis. Evaluations of the devices under ambient conditions showed typical p-channel FET responses with the field-effect mobility higher than 1.0 cm2 V-1 s-1 and Ion/Ioff of approximately 10(7).
2,7-二烷基[1]苯并噻吩并[3,2-b]苯并噻吩被作为可溶液加工的分子半导体进行测试。通过旋涂沉积在Si/SiO2衬底上的有机半导体薄膜具有有序结构，这一点通过X射线衍射分析得以证实。在环境条件下对器件的评估显示出典型的p沟道场效应晶体管响应，场效应迁移率高于1.0 cm2 V-1 s-1，开/关电流比约为10(7)。
