Organic semiconducting materials based on π-extended linear-conjugated systems have been very intriguing and great progressive development has been achieved in these materials for a long time. Therefore, a number of researchers have attempted to synthesize π-conjugated small molecules, dendrimers, oligomers, and polymers because of their strong potential applications to electronics and optoelectronics. In this work, we demonstrate the synthesis of bithiophene based benzodithiophene derivative for use as soluble p-type organic semiconductors in field effect transistors. The geometry and molecular electronic energy levels were confirmed by density functional theory calculation. And we compared their properties with our anthracene based materials studied earlier in our group. We performed the UV-visible spectroscopy, PL spectroscopy, cyclic voltammetry, thermal analyses of the new-conjugated molecule. |
