STRUCTURAL ORDER IN POLY(P-PHENYLENE VINYLENE)

Poly(p-phenylene vinylene) [PPV] is fast becoming one of the most wide ly studied of the conjugated polymers. Its preparation via a precursor polymer synthesis allows ready processing and presents many opportuni ties for subtle control of the physical and electronic properties of t he final polymer. A number of precursor routes have now been developed and we report an X-ray and electron diffraction study of the effects of different synthesis routes on the structure of the PPV polymer film s thus prepared.
