Synthesis and Charge-Carrier Transport Properties of Poly(phosphole P‑alkanesulfonylimide)s

A new class of polyphospholes bearing alkanesulfonylimino moieties on the phosphorus(V) centers was prepared by the Pd–CuI-promoted Stille coupling reaction to investigate the charge-carrier transport properties of the π-networks of polyphospholes. Time-of-flight measurements have revealed that the poly(phosphole P-imide)s possess ambipolar charge-carrier mobilities of up to μelectron = 6 × 10–3 cm2 V–1 s–1 and μhole = 4 × 10–3 cm2 V–1 s–1.
