characterization of several new polymers that are considered one-dimensional prototypes for the polaronicferromagnetic are reported. Synthesis involved either Wittig or Suzuki coupling to produce polymers with extended pi} systems. Oxidative doping (Isub 2} or AsFsub 5}) produces radical cations (polarons) that are stable at room temperature. Magnetic characterization of the dopedpolymers, using SQUID-based
