Regioregular P3HT Semiconductor for Solution-Processed OFETs
Regioregular P3HT (Poly(3-hexylthiophene-2,5-diyl), P2513) is a polymer semiconductor for solution-processed organic electronics. P2513 offers very high regioregularity (RR > 99%) and low metal content (Pd < 100 ppm). In TCI's brochure, it showed the highest hole mobility among six P3HT samples tested, 10.5 ± 0.4 × 10⁻² cm²/Vs in top-contact devices on OTS-treated Si/SiO₂, spin-coated and measured under nitrogen.¹⁴⁾ ¹⁵⁾ It is used as a solution-processed material for organic electronics.¹⁹⁾ ³⁴⁾ In a recent development, gating P3HT with the imidazolium ionic liquid DMIM-BF4 (D5373) as gate dielectric forms an electric double layer that raises carrier density. The DMIM-BF4-gated high-regioregular P3HT device reached a carrier mobility of 20.2 cm²/Vs, the highest reported for a P3HT-based OFET, with operation stability over 40 days under ambient conditions.
