Rieke Metals Polymers
Utilizing Unique Technology for the Preparation of Novel Polythiophenes
One of the world leaders in 3-alkylpolythiophenes, Rieke Metals polymer division is unique in the range of compounds we offer. Our polymer list has grown dramatically in recent years to include water soluble polythiophenes, 3-thioalkyl polythiophenes and regiorandom polythiophenes. We provide several different types of P3HT for research and commercialization and a special 25%-25%-25%-25% regiorandom P3HT. 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 offer:
- Regioregular 3-alkyl polythiophenes
- Regiorandom 3-alkyl polythiophenes
- Water soluble polythiophenes
- 3-Thioalkyl polythiophenes
All of our polymers are found in the 4000’s product numbers and our monomers are found in the 4100's product numbers.

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 groupd chain length, the butyl being the least soluble and the dodecyl being the most soluble. Please feel free to contact us about specific solubility questions.
