A simple and efficient methodology has been developed for the synthesis of β-functionalised terthiophene monomers, conducting polymer precursors. Using a building block approach, the key materials, β-terthiophene aldehyde and phosphonate, were constructed with Suzuki chemistry. Reactions of these building blocks with the appropriate coupling partner under Wittig/Horner-Emmons conditions provides conjugatively-linked functionalised monomers.

An efficient modular strategy has been developed for the synthesis of β-functionalised terthiophene monomers using Suzuki-Miyaura and Wittig/Horner-Emmons chemistries. This paper discusses the problems encountered with converting the β-terthiophene aldehyde building block to the β-terthiophene phosphonium salt and the use of this material in a Wittig condensation. An improved strategy using the β-terthiophene phosphonate building block constructed via Suzuki-Miyaura coupling protocols was developed. We have synthesised and characterised a broad range of functionalised terthiophene materials that have been designed for specific end-use applications. The availability of these building blocks has dramatically increased access to a range of key monomers.
