Synthesis and Charge-Carrier Transport Properties of Poly(phosphole P-alkanesulfonylimide)s
摘要:
A new class of polyphospholes bearing alkanesulfonylimino moieties on the phosphorus(V) centers was prepared by the Pd-Cul-promoted Stille coupling reaction to investigate the charge-carrier transport properties of the pi-networks of polyphospholes. Time-of-flight measurements have revealed that the poly(phosphole P-imide)s possess ambipolar charge-carrier mobilities of up to mu(electron) = 6 x 10(-3) cm(2) V-1 s(-1) and mu(hole) = 4 x 10(-3) cm(2) V-1 s(-1).
