Estimating the term…
The present invention relates to polythiophenes, particularly regioregular head-to-tail poly(3-alkylthiophenes) (HT-PATs), block copolymers made therefrom, and their methods of formation. The present invention provides HT-PATs with well-defined, specific end-groups, functionalization of the defined HT-PATs, and incorporation of end group functionalized HT-PATs into block copolymers with structural polymers. The intrinsically conductive diblock and triblock copolymers, formed from the HT-PATs, have excellent conductivity and low polydispersities that are useful in a number of applications. The block copolymers of the present invention have been found to exhibit conductivities that range from a low of 10−8 S/cm for certain applications to as high as several hundred S/cm or more.

A method of forming a polymer, comprising:
A composition comprising a regioregular polythiophene having at least 90% H/H end groups by weight, wherein the polythiophene is represented by:
A composition comprising a regioregular polythiophene having at least 90% H/H end groups by weight, wherein the polythiophene comprises 3-substituted thiophenes in which the 3-substituent is an ether or aryl group.
A method of forming a regioregular polythiophene with H/H end groups, comprising:
