Convenient synthesis for the end-functionalization of P3HT

Principal Investigator: Christine Luscombe

The functionality of an end group on a polymer can help determine the application of the polymer. Polymers that are pi-conjugated have semiconducting properties. This means that resulting materials can combine the mechanical properties of polymers with electrical and optical properties, and thus have the potential for wide applicability, especially in optoelectronics. Despite some advancements, there still exists a need for a method to create specifically end-capped, pi-conjugated polymers conveniently. To fulfill this need, the investigators provide methods for mono- and bis-end-functionalization of pi-conjugated polymers with chalcogen.

Separate methods are provided for the preparation of mono-end functionalized, pi-conjugated polymers and for bis-end-functionalized pi-conjugated polymers. Chalcogens, sulfur and selenium for example, are selectively added to the terminus, or end, of the polymer. In both methods, the polymers are formed by Kumada catalyst transfer polymerization.

• This method could be used in the process of creating organic printable electronics, for example in OLEDs. 

• This technology could also be used in the development of photovoltaic cells. 

• This method could be used in the materials in field-effect transistors.
