  1. 1. Conjugated polyelectrolytes : conformation sensitive optical probes for the recording of biological processes

    Författare :Peter Nilsson; Guillermo C. Bazan; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : The physical properties of conjugated polymers can be utilized for a wide range of biosensors. For instance, the conformational flexibility fouud in conjugated polyelectrolytes, allows direct connection between the geometry of chains and the resulting electronic structure and optical processes, since the extension of the π-conjugated system is distorted by conformational changes of the polyelectrolyte backbone.

  2. 2. Electroactive Conjugated Polyelectrolytes Based on EDOT From Synthesis to Organic Electronics

    Författare :Roger Gabrielsson; Peter Konradsson; Olle Inganäs; David Mecerreyes; Linköpings universitet; []
    Nyckelord :Conjugated polyelectrolytes; Electroactive conjugated polyelectrolytes; Intrinsically conducting polyelectrolytes;

    Sammanfattning : Conjugated polyelectrolytes (CP) show interesting electrical and optical properties for organic electronics as well as for life science applications. Their possibilities of supramolecular assembly with nanowire like misfolded proteins, amyloids, as well as synthetic polypeptides or DNA forming conducting nano composites is highly interesting as being a truly bottom up approach for fabrication of OLEDs, photovoltaic’s as well as logic devices.
