Description

General description

Poly(3-hexylthiophene) (P3HT) is a regioregular semiconducting polymer. It is used in organic electronics primarily because of its regular end-to-end arrangement of side chain, which allows efficient p- p stacking of the conjugated backbones. On account of the alkyl side group, P3HT is rendered hydrophobic in neutral state. Solution-to-solid phase transformation and thin film formation of poly(3-hexylthiophene) (P3HT) was reported in a study.

Poly(3-hexylthiophene-2,5-diyl) (P3HT) is a poly(alkylthiophene) based semiconducting polymer that is hydrophobic at neutral state and has π-π conjugation in its backbone. It has a hole mobility is in the range of 10^-3-10^-1 cm²V^-1s^-1 and is commonly used in the development of field-effect transistors (FETs) for a wide range of applications.

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product belongs to Enabling category of greener alternatives thus aligns with "Design for energy efficency". Hole transport organic materials allow perfect energy level alignment with the absorber layer and therefore efficient charge collection, are prone to degradation in ambient conditions.Click here for more information.

Application

For the characterization and solid-state properties of this polymer, see J. Am. Chem. Soc. .

P3HT, an electron donor that acts as a semiconducting active layer in combination with an electron acceptor like fullerene derivative (6,6)-phenyl C61-butyric acid methylester (PCBM), can be used to fabricate bulk heterojunction (HJT) based organic solar cells (OSCs). Volatile organic compounds (VOCs)and electric sensor devices can be developed by using Langmuir-Schaefer (LS) films of P3HT and poly(3-octylthiophene)(P3OT). It can also be used with polystyrene to process a nano-scaled polymeric coating through spray coating onto carbon nanotube (CNT) powders.

Poly(3-hexylthiophene-2,5-diyl) may be used to fabricate ZnO nanowire arrays based photodiode. Regio- regular poly(3-hexylthiophene-2,5-diyl) may find extensive use as a semiconducting layer in organic thin film field effect transistor (FETs).

Rechargeable battery electrodes, electrochromic devices, chemical and optical sensors, light-emitting diodes, microelectrical amplifiers, field-effect transistors and non-linear optical materials.
