  2. 11. Conjugated polymers with functional side chains for photovoltaics

    Author : Kim Bini; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; side chain engineering; polymer solar cells; green solvent solubility; transmission electron microscopy; conjugated polymers;

    Abstract : Polymer solar cells are quickly approaching viability as a large scale electrical power source. To increase their stability and processability in green solvents, we want to modify their solubilizing side chains with different functionalities. READ MORE

  4. 12. Synthetically simple conjugated polymers for organic electrochemical transistors

    Author : Joost Kimpel; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; organic electrochemical transistors; direct arylation polymerization; conjugated polymers; synthetic complexity index;

    Abstract : The soft and flexible nature of organic materials makes them suitable for the integration into wearable or implantable devices. This paves the way for the development of next-generation bioelectronic systems for e.g. medical diagnostics. READ MORE

  5. 13. Conjugated Polymers, Amyloid Detection and Assembly of Biomolecular Nanowires

    Author : Anna Herland; Olle Inganäs; Samuel I. Stupp; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Conjugated Polymers; Amyloid Fibrils; Nanowires; Self-Assembly; Sensor; Amyloid Detection; Physics; Fysik;

    Abstract : The research field of conjugated polymers has grown due to the optical and electronic properties of the material, useful in applications such as solar cells and printed electronics, but also in biosensors and for interactions with biomolecules. In this thesis conjugated polymers have been used in two related topics; to detect conformational changes in proteins and to assemble the polymers with biomolecules into nanowires. READ MORE

  6. 14. Synthesis of Conjugated Polymers: Photoactive Substances for Photonic Devices

    Author : Mikael Johansson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; synthesis; microcavity laser devices; electroluminescence; conjugated polymers; light-emitting diodes; photoluminescence; photooxidation; energy transfer;

    Abstract : Synthesis and characterization of conjugated polymers are the subject of this thesis, the goal of which is to synthesize polymers with properties that will make them suitable as the active materials in applications such as light-emitting diodes and microcavity laser devices. The two classes of conjugated polymers studied are poly(p-phenylenevinylenes) (PPVs) and polyfluorenes (PFs). READ MORE

  7. 15. Synthesis and Properties of Conjugated Polymers for Photonic Devices

    Author : Mattias Svensson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; conjugated polymers; polyfluorenes; light-emitting diodes; solar cells; photoluminescence; electroluminescence; polythiophenes;

    Abstract : The synthesis and properties of new conjugated polymers for photonic devices, such as light-emitting diodes and solar cells is dealt with here. Much work was devoted to increasing the efficiencies of the devices by controlling the properties in thin films of the polymers. READ MORE
