Abstract
The invention relates to a novel process for the production of linear organic thiophene-phenylene oligomers represented by the following general formula (I),The process involves reacting (e.g., by means of a Suzuki coupling reaction) a compound represented by the following general formula (II),with a formula represented by the following general formula (III),The reaction may be conducted optionally in the presence of catalysts, optionally in a solution and/or optionally at elevated temperature. The linear organic thiophene-phenylene oligomers of the present invention may be used to form semi-conductive coatings.
