Reverse evolution of fluorine and side chains in bisisoindigo‐based copolymers enabling electron mobility exceeding 7 cm2·V−1·s−1

open access: yesFlexMat, EarlyView.
Abstract We report the design and synthesis of a series of bisisoindigo‐based donor–acceptor (D–A) copolymers, P4F18, P4F10, P2F18, and P2F10. By reverse evolution of fluorine substitution and side‐chain structure, we effectively tuned the frontier molecular orbital energy levels, intermolecular interactions, molecular self‐assembly, and thus charge ...
