説明

<jats:title>Abstract</jats:title> <jats:p>2,6-Dialkyl[1,2-b:4,5-b′]dithiophenes were synthesized as novel solution-processible organic 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 of ca. 10−2 cm2 V−1 s−1 and Ion⁄Ioff of ca. 105.</jats:p>
