Synthetic Chemistry for Ultrapure, Processable, and High Mobility Organic Semiconductors

This is an invited article to be published in Accounts of Chemical Research. An essential aspect of our development of organic-based electronics has been the synthetic chemistry devised for the preparation of key semiconductor materials. Access to organic semiconductors in sufficient purity and variety has led to breakthroughs in solid state physics and circuit realization. In this manuscript, we review the synthetic methods research that we have conducted for this purpose. Thiophene oligomers, fused ring compounds, and polymers are discussed.
