A series of alkoxy-substituted poly(p-phenylene vinylenes) have been synthesized using unique chemical methodologies. Although the end polymers were structurally the same, small deviations were noticed upon characterization depending on the method of synthesis. Variations in molecular weight, defect sites (determined through quantum yield and NMR analysis), and absorbance/emission maxima were found to be a function of the polymerization chemistry.

520 $a A series of alkoxy-substituted poly(p-phenylene vinylenes) have been synthesized using unique chemical methodologies. Although the end polymers were structurally the same, small deviations were noticed upon characterization depending on the method of synthesis. Variations in molecular weight, defect sites (determined through quantum yield and NMR analysis), and absorbance/emission maxima were found to be a function of the polymerization chemistry.
520 $a Three different synthetic routes were used to produce this series: a Wittig salt/sulfonium aldehyde condensation polymerization, a ruthenium metathesis of a divinylbenzene derivative, and thermolysis of a polyazine precursor polymer made through a condensation of bis-benzaldehyde and hydrazine. It was found that the metathesis route provided low molecular weight polymers, but with relatively few defect sites giving them high quantum efficiencies. The polyazine thermolysis method gave very high molecular weight polymers (the precursor itself also has a high molecular weight), but relatively low quantum efficiencies. The modified Wittig route gave quantum efficiencies and molecular weights in range with literature findings, but was plagued with sulfur contamination.
