Organic semiconductor materials based on extended linear-conjugated systems have been very intriguing and significant development has been achieved in these materials over the last several years. In the exploration of the application as organic semiconductors in organic field effect transistor (OFET) is an important component for developing future flexible displays. Organic photovoltaic cell is also promising candidate device for future energy resources. In organic semiconductors, the intrinsic carrier mobility depends critically on the degree of molecular orientation and on the extent of the intermolecular interaction. In this study, new p-type conjugated polymers have been synthesized through Stille coupling reaction. They display a p-type semiconducting behavior and have much better solubility than the other linear conjugated oligothiophene. We perform absorption spectroscopic analysis, electrochemical analysis. Finally, the OTFT devices performances were investigated. |
