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

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

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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). LÄS MER

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

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

    Sammanfattning : 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. LÄS MER
