摘要
Monosilanylene-oligothienylene alternating polymers, [T-x-(SiBu2)](n) (MSxT, T = 2,5-thienylene or 3-butyl-2,5-thienylene, x = 8, 10, 12, and 14), were synthesized and their applications to electroluminescent (EL) devices and field effect transistors (FETs) were examined. The onset voltages for the luminance of EL devices with the structure of ITO/MSxT/Alq3/Mg:Ag were reduced on going from x = 10 to 14. However, the highest maximum luminance was achieved for x = 12 (900 cd/m(2)). The field effect carrier mobilities of the MSxT films were determined to be (3.4-6.9) x 10(-5) cm(2) V-1 s(-1), which increased with the length of the oligothiophene unit from x = 8 to 12, while increasing x from 12 to 14 barely affected the FET properties.
