  • Organic electronic devices prepared using decomposable polymer additives
    Patent number: 9260443
    Abstract: A method of fabricating an organic device is provided comprising providing a first solution comprising an organic semiconductor or a precursor thereof; a solvent and a decomposable polymer additive, where the polymer additive is heated so that it decomposes into gas. The method is applicable to large scale fabrication of OLEDs, OPVs and OFET devices.

  • MODULAR STRATEGY FOR INTRODUCING END-GROUP FUNCTIONALITY INTO CONJUGATED COPOLYMERS
    Publication number: 20130248833
    Abstract: The invention provides methods for making and using end-functionalized conjugated polymers. Embodiments of the invention comprise performing a coupling polymerization in the presence of AA monomers, BB monomers and an end capping compound that can react with a monomer and which is selected to include a functional group. The functional end groups can, for example, comprise polymers or small molecules selected for their ability to produce conjugated polymers that self-assemble into thermodynamically ordered structures. In certain embodiments of the invention, nano-scale morphology of such conjugated polymer compositions can be driven by the phase separation of two covalently bound polymer blocks. These features make the use of conjugated polymers an appealing strategy for exerting control over active layer morphology in semiconducting polymer materials systems.
