A family of four new DA polymers, in which the acceptor moiety benzobisthiadiazole was paired with four different donor moieties, has been synthesized. Surprisingly, all members of the family exhibit balanced ambipolar behavior, despite polymer to polymer mobilities varying from 10−4 cm2 V−1 s−1 to 10−1 cm2 V−1 s−1. Applications in single component CMOS integrated circuits are envisioned.
