Poly p phenylene vinylene synthesis

WebSep 1, 2011 · WSCPs can be synthesized by attaching hydrophilic side chains to the conjugated polymer backbone. This approach has been used for various conjugated structures such as poly(p-phenylene vinylene) [22], poly(p-phenylene) [23], poly(p-phenylene ethylene) [24], polyfluorene [25] and polythiophene [26] based polymers. WebNov 1, 2009 · A cationic poly(p-phenylene vinylene) related copolymer without bulky phenylene substitutents attached to the conjugated backbone was prepared through Wittig reaction.

WebA new approach to PPV was envisioned through the ROMP of “barrelene” (bicyclo[2.2.2]octa-2,5,7-triene) (1).The corresponding polymer, which is formally a copolymer that consists of alternating 1,4-cyclohexadienyl and vinylene repeat units, should be prone to aromatization via dehydrogenation and thus may transform to PPV under relatively mild conditions. Poly(p-phenylene vinylene) (PPV, or polyphenylene vinylene) is a conducting polymer of the rigid-rod polymer family. PPV is the only polymer of this type that can be processed into a highly ordered crystalline thin film. PPV and its derivatives are electrically conducting upon doping. Although insoluble in water, its precursors can be manipulated in aqueous solution. The small optical band …
