Synthesis and electroconductivities of poly(2‐methoxy‐5‐methythio‐1,4‐phenylene vinylene) and copolymers

Abstract

AbstractPoly(2‐methoxy‐5‐methylthio‐1,4‐phenylene vinylene), PMTPV, and copolymers containing both unsubstituted or 2,5‐dimethoxy‐substituted and 2‐methoxy‐5‐methylthio‐1,4‐phenylene vinylene units were prepared in thin films from their water‐soluble, sulfonium salt precursor polymers. Doping of drawn and undrawn films of PMTPV with I2 vapor led to conductivities of 10−4–10−3 S cm−1, which is significantly lower than those reported for poly(2,5‐dimethoxy‐1,4‐phenylene vinylene). Conductivity of I2‐doped copolymer films ranges from 10−3–100 S cm−1 depending on composition.
