Polymeric materials have recently shown promise as the active layer in organic based thin film transistors and organic field effect transistors. Among the large class of semiconductors, benzodithiophene and its derivatives are evaluated to be high stability and oxidation potentials. Moreover, benzodithiophene has π-π stacking orderness for efficient charge carrier transport to obtain high field-effect transistor mobility. So, apart from the combination with 3-alkylthiophene or 9,9’-dialkylfluorene units is an improving solution processability and π-electron delocalization. Therefore, the polymers based on benzodithiophene and 3-alkylthiophene or 9,9’-dialkylfluorene have been synthesized by oxidative and Suzuki coupling polymerization, and determined from FT-IR, NMR, and elemental analysis. Furthermore, physical, optical and electrochemical properties will be discussed. The polymers will have performed for OTFT device with expecting high mobility. |
