Abstract

Incorporation of acceptor‐acceptor (A‐A) type moieties into donor‐acceptor (D‐A) type conjugated polymers becomes a new strategy to tune their electronic properties. In this work, we first demonstrate an efficient convergent route to prepare isoindigo‐based A‐A type building blocks ‐ bis‐isoindigos ‐ via the palladium‐catalyzed oxidative coupling. Bis‐isoindigo‐based polymers show high planarity and delocalized frontier molecular orbitals with lowered LUMO and intact HOMO energy levels, in comparison with their corresponding mono‐isoindigo counterparts. Moreover, fluorine substitution on donors only lowers HOMO levels of Bis‐IID polymers. This study asserts that the D‐A‐A strategy is effective in selectively tuning FMO energy levels of conjugated polymers, complementary to the D‐D‐A approach for the HOMO energy level tuning.
