Highly Regioselective Organic Semiconducting Polymer: P3HT

Poly(3-hexylthiophene) (P3HT, 1) is widely useful in organic electronics research fields, and is a representative material of soluble organic semiconducting polymers. The performance of electronic materials is typically dependent on the quality of the material. Among them, purity and molecular weight are important factors for the material performance. 1 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, 1 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.
