Study on the Synthesis of Poly(p-Phenylene Vinylene) Derivatives by Dehydrochlorination

The synthesis of poly(p-phenylene vinylene) (PPV) and its derivatives have aroused great interest^1],since Burroughes^2] discovered that PPV showed excellent electroluminescent (EL) properties. The conventional polymerization reactions, such as dehydrochlorination reaction,Wittig reaction and et al, usually afforded insoluble and/or infusible PPV and its derivatives, which shows inferior mechanical properties. Though the precursor polymer route can circumvent the insolubility of PPV, the strategy needs muti-step reaction and high temperature which affords the low yield and other disadvantageous^3]. So the synthesis of soluble PPV derivatives with high yield are very fascinating.
