3,3′-(Ethane-1,2-diylidene)bis(indolin-2-one) based conjugated polymers for organic thin film transistors†
Abstract
3,3′-(Ethane-1,2-diylidene)bis(indolin-2-one) (EBI) was used as a new electron-acceptor building block for conjugated polymers. Copolymers of EBI and bithiophene exhibited p-type semiconductor performance with hole mobility of up to 0.044 cm2 V−1 s−1 in organic thin film transistors.
