Abstract
An essential aspect of the development of organic based electronics is the synthetic chemistry devised for the preparation of the semiconductor materi als responsible for the activity of organic field-effect transistors. Acces s to organic semiconductors in sufficient purity and variety has led to bre akthroughs in solid-state physics and circuit realization. In this Account, we review the synthetic methods that have been most useful for preparing a range of semiconductors, including thiophene-based oligomers, several kind s of fused rings, and polymers. The tradeoff between process efficiency and target purity is emphasized.
