  Ethynylene-containing benzo[1,2-b:4,5-b′]dithiophene derivatives 1a–c (BPEBDT, BTEBDT and BHPEBDT) were designed and synthesized. Their physicochemical properties were studied by absorption spectra and electrochemistry. 1a–c displayed high field-effect transistors performance, a mobility up to 1.17 cm2 V−1 s−1 with on/off current ratio of 107 was achieved.
