Semi-conducting Polymers and Monomers
Organic Semi-conducting Polymers and Monomers
Today’s Materials for Tomorrow’s Electronics™
One of the world leaders in 3-alkylpolythiophenes and P3HT, Rieke Metals’ polymer division is unique in the range of compounds offered. Our polymer list includes water soluble polythiophenes, 3-thioalkyl polythiophenes and regiorandom polythiophenes.
We provide many different types of P3HT for research and commercialization and a special 25%-25%-25%-25% regiorandom P3HT. Our newest grade of P3HT, RMI-001E/EE, has a regioregularity of 96% or above. All the polymers are characterized by high regioregularity and reproducibility. The monomer list has also been expanded and includes 2,5-dibromo-3-alkylthiophene in addition to many other substituted monomers.

We are proud to list the below article published in Nature. Published on November 9, this paper’s research was done using Rieke Metals’ P3HT.
“Highly Conductive Graphene/Ag Hybrid Fibers for Flexible Fiber-Type Transistors.” Sang, S.Y. et al, Nature Scientific Reports 5, Article number: 16366, 2015.
These semi-conducting polymers are useful for, but not limited to, printed electronics, OLED’s, RFID tags and photovoltaic cells (solar cells). For more information on the uses of P3HT, see our “References” page.
Rieke Metals offers several classes of specialty semi-conducting polymers.
Poly(3-hexylthiophene-2,5-diyl) or P3HT, regioregular or regiorandom
Please contact us for P3HT batch specific information.
4002-E and 4002-EE, P3HT regioregular
Molecular weight (Mw):
Approximately 50-70K via GPC
(We have batches with Mw values outside of this range, so please contact us if you want higher or lower molecular weights)
Regioregularity:
91-94% via NMR
Metal contents (Br, Ni and Zn):
The “E” series typically contains less than 0.02%
The “EE” series typically contains less than 0.01%
4007, P3HT regiorandom
Molecular weight (Mw):
Approximately 60-95K via GPC
PDI:
2.8-3.1
RMI-001E and RMI-001EE, P3HT regioregular
Molecular weight (Mw):
We have batches that range from 36K to 90K via GPC. All batches are priced the same. Please contact us for specific batch information.
Regioregularity:
Approximately 96% or above via NMR
EE version has undergone an additional purification process.
RMI-002E and RMIE-002EE, P3HT regioregular
Molecular weight (Mw):
Approximately 25-40K via GPC
Regioregularity:
89-94% or above via NMR
EE version has undergone an additional purification process.
Solubility:
P3HT is not soluble in protic solutions, such as alcohols. It is most soluble in chlorinated hydrocarbons such as chloroform, methylene chloride and carbon tetrachloride. P3HT is reasonably soluble in THF and also aromatic hydrocarbon solvents such as toluene and xylene. The regiorandom version is more soluble than the regioregular versions. Please feel free to contact us about specific P3HT solubility questions.

Poly(3-alkylthiophene-2,5-diyl), regioregular or regiorandom
Alkyl = butyl, octyl, decyl, and docecyl.
Molecular weight (Mw):
Approximately 45-60K via GPC
Regioregularity unless otherwise noted:
91-94% via NMR
Metal contents (Br, Ni and Zn):
The “regular” series typically contains less than 0.2%
The “E” series typically contains less than 0.02%
Solubility:
These polymers are not soluble in protic solutions, such as alcohols. They are most soluble in chlorinated hydrocarbons such as chloroform, methylene chloride and carbon tetrachloride. They are reasonably soluble in THF and also aromatic hydrocarbon solvents such as toluene and xylene. The solubility differs with the 3-alkyl group chain length, the butyl being the least soluble and the dodecyl being the most soluble. The regiorandom versions are more soluble than the regioregular versions. Please feel free to contact us about specific solubility questions.
