Donor−acceptor (D−A) alternating copolymers are the most promising and attractive materials for electronic and optoelectronic applications in recent years. As a molecular component, thieno[3,4-b]thiophene (TT) unit extends the backbone planarity and promotes the delocalized electron distribution along a polymer backbone. Also, anthracene (ANT) unit affects the chain-packing and alignment behavior. In this study, we demonstrate synthesis and characteristics of TT-ANT-based conjugated polymer. The effect of anchoring position of TT unit from the 2,6- to the 9,10-position in the anthracene ring was investigated on the semiconducting property. Therefore, we investigated their physical properties by thermal analysis, cyclic voltammetry and absorption spectroscopy. Eventually, we successfully fabricated field-effect transistor devices to study their charge transport properties. |
