Abstract

Electron transporting (n-channel) polymer semiconductors for field-effect transistors are rare. In this investigation, the synthesis and characterization of new electron-depleted N-alkyl-2, 2′-bithiophene-3, 3′-dicarboximide-based π-conjugated homopolymers and copolymers containing the 2, 2′-bithiophene unit are reported. A novel design approach is employed using computational modeling to identify favorable monomer properties such as core ...
