Various synthetic methodologies involving organometallic reagents and leading to conjugated oligomers and polymers are presented. Polyenes and oligomers of poly(paraphenylenevinylene) with well-defined length of the conjugated system were prepared by straightforward synthetic procedures based upon organometallic derivatives of silicon or boron. Fluorinated oligo(para-phenylenes) containing up to five aromatic rings were easily obtained by homocoupling reaction promoted by copper(I) thiophenecarboxylate. The Stille cross-coupling reaction was applied to the synthesis of poly(para-phenylenevinylene) polymers with various substituents on the aromatic rings. Some relevant electro-optical properties of these materials are also discussed.

Abstract

Various synthetic methodologies involving organometallic reagents and leading to conjugated oligomers and polymers are presented. Polyenes and oligomers of poly(paraphenylenevinylene) with well-defined length of the conjugated system were prepared by straightforward synthetic procedures based upon organometallic derivatives of silicon or boron. Fluorinated oligo(para-phenylenes) containing up to five aromatic rings were easily obtained by homocoupling reaction promoted by copper(I) thiophenecarboxylate. The Stille cross-coupling reaction was applied to the synthesis of poly(para-phenylenevinylene) polymers with various substituents on the aromatic rings. Some relevant electro-optical properties of these materials are also discussed.
