Utilizing Unique Technology for the Preparation of Novel Polythiophenes

Rieke Metals, Inc. employs unique chemical technology for the production of highly reactive metals. These metals allow us to prepare a wide range of novel organometallic reagents. Using these organometallic reagents, Rieke Metals can prepare a broad spectrum of polymers including 3-alkyl polythiophenes. Additionally, this technology allows us to prepare a large number of functionalized 3-alkyl polythiophenes which display a wide range of electrical properties. All of our polythiophenes are characterized by high quality and reproducibility. We can supply grams to multi-kilograms.

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


Polythiophene Information For

 

P-100 (P3HT):            ~95% regioregular
                            Average molcular weight: 50,000 Mw
                            Metal content is approximately 50 ppm

P-200 (P3HT):           >98% regioregular
                           Average molecular weight: < 50,000 Mw
                            Metal content is approximately 50 ppm     


Poly (3-butylthiophene-2, 5-diyl), Catalog number 4001, 4001-E

Poly (3-hexylthiophene-2,5-diyl), Catalog number 4002, 4002-E, 4002-EE
Poly (3-octylthiophene-2, 5-diyl), Catalog number 4003, 4003-E
Poly (3-decylthiophene-2, 5-diyl), Catalog number 4004, 4004-E
Poly (3-dodecylthiophene-2, 5-diyl), Catalog number 4005, 4005-E

Molecular weight (Mw):
Approximately 55-60K via GPC

Regioregularity:
93-95%. Further purification can raise the number to 98%

Metal contents:
The "regular" series typically contains less than 0.2%

The "E" series typically contains less than 00.02%

Please note: All series have the same molecular weight and regioregularity. They only differ with metal ion content.


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.
