Assignee:

Carnegie Mellon University - Pittsburgh PA

International Classification:

C08G 1864

US Classification:

528 73, 525417, 525535, 525536, 528377, 528378, 528379

Abstract:

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 S/cm for certain applications to as high as several hundred S/cm or more.

International Classification:

C08F 6/00

US Classification:

528491, 528480, 528482, 252500, 210638, 210688

Abstract:

Metal complexing agents are used to purify polymers including conducting polymers to provide very low metal content. The process comprises precipitating the polymer in solution into a solvent system comprising the metal complexing agent. Very low levels including undetectable levels of metals such as nickel and magnesium can be achieved. High purity polymers are used in electronics and photovoltaic applications.

Abstract:

Universal Grignard Metathesis (GRIM) reactions which provide access to conjugated polymers by GRIM methods. A method comprising: providing an unsaturated ring compound comprising at least two halogen ring substituents, providing an organomagnesium reagent comprising an organomagnesium component and a metal activation agent, combining the unsaturated ring compound with the reagent to form a second compound by metal-halogen exchange, wherein the metal activation agent activates the metal-halogen exchange, coupling the second compound to itself in an oligomerization or polymerization reaction. Metal activation agent can be lithium chloride. The process is commercially attractive and can be executed in good yields. Polyfluorenes, polypyrroles, and polythiophenes can be prepared for use in OLED, PLED, photovoltaic, transistor, antistatic coatings, and sensor applications.
