Abstract

We show that selenophene-substitution can be an efficient synthetic strategy toward high charge carrier mobility of isoindigo (IID)-based copolymers when their side chains are optimized. A high mobility of 5.8 cm2 V−1 s−1 is demonstrated by a strategically designed IID-based polymer, with both side-chain adjustment and selenophene-substitution.
