Examples of the self-assembled copolymers include a diblock copolymer or bottlebrush copolymer including the first block covalently bonded to the second block.

Abstract: A composition of matter including a crosslinked bottlebrush polymer, wherein the crosslinker units in the composition of matter are soluble with the bottlebrush polymer. In one example, the crosslinked bottlebrush polymer is tailored as a single phase (solvent free) elastomer useful in a capacitive pressure sensing device. A novel embodiment of the present invention further includes demonstration of a universal approach to form solvent-free bottlebrush polymer networks by photo-crosslinking mixtures of well-defined bottlebrush precursors and bis-benzophenone-based additives. This method has been proven effective with a wide variety of different side-chain chemistries.

Abstract: A method for enhancing charge carrier mobility of a field-effect transistor device. The method comprises generating uniaxial nanogrooves on a substrate and blade coating a solution comprising a semiconducting polymer onto the substrate. The polymer solution is spread onto the substrate in a direction parallel to the nanogrooves and a main-chain axis of the polymer is parallel to the nanogrooves. The semiconducting polymer can be then annealed, so that a polymer film is formed which is layered on top of the substrate, with polymer chains aligned parallel to a direction of charge carrier movement.

Abstract: Triazabicylodecene can effectively n-dope a variety of organic semiconductors, including PCBM, thus increasing in-plane conductivities. We synthesized a series of TBD-based n-dopants via an N-alkylation reaction and studied the effect of various alkyl chains on the physical and device properties of the dopants. Combining two TBD moieties on a long alky chain gave a solid dopant, 2TBD-C10, with high thermal stability above 250° C. PCBM films doped by 2TBD-C10 were the most tolerant to thermal annealing and reached in-plane conductivities of 6.5×10−2 S/cm. Furthermore, incorporating 2TBD-C10 doped PCBM as the electron transport layer (ETL) in methylammonium lead triiodide (MAPbI3) based photovoltaics led to a 23% increase in performance, from 11.8% to 14.5% PCE.

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.
