title: Novel stable (3E,7E)-3,7-bis(2-oxoindolin-3-ylidene)benzo[1,2-b:4,5-b']difuran-2,6(3H,7H)-dione based donor-acceptor polymer semiconductors for n-type organic thin film transistors.
abstract: (3E,7E)-3,7-Bis(2-oxoindolin-3-ylidene)benzo[1,2-b:4,5-b']difuran-2,6(3H,7H)-dione (IBDF) was used as a new electron-acceptor building block for polymer semiconductors with very low-lying energy levels. A copolymer of IBDF and thiophene showed stable electron transport performance in thin film transistors.
