Polaron-Type Magnetic Conjugated Polymer with Liquid Crystallinity

We synthesized poly(para- and meta-phenylenevinylene) derivative with liquid crystalline group. The polymeris composed of p-phenylenevinylene as a spin generating unit and m- phenyleneas a ferromagnetic spin coupling unit. The polymershowed nematic LC phase. The polymerwas doped by iodine to generate the polaron, after the polymerwas cooled downthrough the LC phase. ESR measurements showed that the spin concentration increased by means of external magnetic force alignment of the polymer.
