摘要：
trans-trans-2,5-Bis-[2-{5-(2,2'-bithienyl)}ethenyl]thiophene (BTET) was synthesized and then purified in a gradient sublimation system. It was characterized using IR, UV-Vis and mass spectroscopy, and elemental analysis. BTET films were deposited with molecular beam deposition (MBD) or spin-coating from solution. Insulated-gate field-effect transistor (IGFET) devices based on such films were used to study their electrical transport properties. A field-effect mobility of 0.01 cm(2) V-1 s(-1) was measured from films deposited with MBD, while the mobility of the spin-coated films was slightly above 0.001 cm(2) V-1 s(-1).
