2，7-二烷基[1]苯并噻吩并[3，2-B]苯并噻吩作为可溶液加工的分子半导体被测试。通过旋涂法在Si/SiO2衬底上沉积的有机半导体薄膜具有良好的有序结构，XRD分析证实。在环境条件下对器件的评估显示出典型的p沟道FET响应，场效应迁移率高于1.0 cm（2）V-1 S-1，并且/（n）//（off）为-10（7）。
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 cm(2) V-1 S-1 and /(n)//(off) of -10(7).
