Regioregular Organic Semiconducting Polymer as Donor and Hole Transport Material
Regioregular P3HT (P2513) is an organic semiconducting polymer with very high regioregularity. It is prepared by direct arylation polymerization (DArP)¹) and offers RR >99.0%, Mn 27,000–45,000, and electronic-grade purity with Pd <100 ppm. Its high solubility allows solution processing and excellent film formation. In organic photovoltaics (OPV), P3HT serves as a donor that forms a bulk heterojunction (BHJ) with a highly soluble acceptor³),⁴). In perovskite solar cells (PSC), it is used as a hole transport material (HTM)⁵), while in organic field-effect transistors (OFET) it functions as a p-type semiconductor⁶). Compared with the Rieke and GRIM methods, DArP-prepared P3HT reaches RR 99.5%, Tm 237 °C, and µmax 0.19 cm²/V·s, whereas the Rieke and GRIM methods give 0.02 and 0.11 cm²/V·s, respectively¹),²).
