Highly Regioselective Organic Semiconducting Polymer: P3HT

P3HT was synthesized by a direct arylation polymerization (DArP)1,2) and features a highly regioselective structure with a consistent average molecular weight and polydispersity index. In addition, P3HT is useful for solution process-able organic solar cells,3,4) perovskite solar cells,5) and organic transistor research,6) due in part to its high solubility.
