摘要: Benzo[1,2-b:4,5-b']diselenophene (BDS) has been incorporated for the first time in a polymer. bis(Stannyl)-functionalized BDS was copolymerized with 3,3'-bis(alkyl)-5,5'-bithiophenes (dodecyl and tetradecyl side chains) through Stille copolymerization, to yield p-type polymer semiconductors organic field-effect transistor application. The electronic structural effect of selenium atoms, compared sulphur atoms analogous copolymers, is described. molecular weight decisive influence on photophysical properties supramolecular ordering, expressed measurements. Saturation mobilities around 10 ―2 cm 2 ·V ―1 s are obtained standard silicon substrates.
