Abstract

The preparation of a high molecular weight soluble derivative of poly(p-xylylene) by vapor phase pyrolysis followed by chemical vapor deposition (CVD) and its dehydrogenation with 1,2-dichloro-3,4-dicyanoquinone (DDQ) to yield the corresponding derivative of poly(phenylenevinylene) is reported. Derivatives of poly(phenylenevinylene)s with nonconjugated segments were prepared by partial dehydrogenation with substoichiometric amounts of DDQ. The thermal and optical properties of segmented and nonsegmented poly(p-phenylenevinylene)s are compared as well as their electroluminescence properties with particular focus on the quantum yields.
