Synthesis and physical properties of poly(phenylene vinylene)s having oligo(ethylene oxide) in the side chain

Oligo(ethylene oxide) chains were introduced into the phenyl ring of the poly(phenylene vinylene) (PPV) derivatives to obtain electronic and ionic conductive liquid crystalline PPV derivatives. Thermal decomposition of all PPV derivatives occurred before isotropic melt. A typical texture of the liquid crystalline phase was not shown but birefringence was observed below the thermal decomposition temperature. Exhibition of a smectic phase for the polymers having triethylene or tetraethylene oxide chains was supported by X-ray measurements. Electronic conductivity of the PPV derivatives doped with I 2 and ionic conductivity of the mixture of these polymers and LiClO4 were also discussed.
