Descripción general

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.
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.


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

Certificado de Análisis

Certificado de origen

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. What is the molecular weight of Product 445703, Poly(3-hexylthiophene-2,5-diyl)?

    The molecular weight (MW) is approximately 87,000. 

  4. What is Product 445703, Poly(3-hexylthiophene-2,5-diyl), soluble in?

    This product will be soluble in Carbon Tetrachloride, Chloroform, and Dichloromethane. It is also partially soluble in Tetrahydrofuran, ether and slightly soluble in Toluene.

  5. For Product 445703, Poly(3-hexylthiophene-2,5-diyl), what does regioregular mean?

    Regioregular means all of the monomer units are in the same orientation.  E.g. if you think of each monomer unit as your palm, regioregular would have all palms facing away, fingers up - all in same orientation.  (Regiorandom might have one pointing up, one pointing down, one with palms facing you, one with palms facing away, etc, all in a row.)

  6. What percentage is regioregular in Product 445703, Poly(3-hexylthiophene-2,5-diyl)?

    Based on proton NMR, it is estimated to be approximately 98% regioregular.

  7. For Product 445703, Poly(3-hexylthiophene-2,5-diyl), what does "diyl" refer to?

    The use of "diyl" is simply an extension of the use of the "yl" ending for a single substituent. For example, a monosubstituted ethane becomes ethyl - - - -, a monosubstituted propane becomes propyl - - - -, a monosubstituted butane becomes butyl - - - - and so on. Similarly, a 1,3-disubstituted butane becomes 1,3-butanediyl, indicating the presence of similar substituents on the 1- and 3- positions of the butane portion of the molecule.

  8. How do I find price and availability?
