    The column "Uni aktuell" points out the publication of AK Sommer in the journal "Nature Communications"

  • 16.05.2019
    New Publication in Adv. Funct. Mater. released: Homocoupling defects in a conjugated polymer limit exciton diffusion

  • 29.07.2019
    New Publication in Nat. Commun. released: Microstructural control suppresses thermal activation of electron transport at room temperature in polymer transistors.

  • 14.06.2019
    New Publication in ACS Appl. Polym. Mater. released: Impact of competing crystallization processes on the structure of all-conjugated donor-acceptor block copolymers P3HT-b-PNDIT2 in highly oriented thin films.

  • New coverpicture von A. Sanzone et al. released.

    The work "Preparation of Naphthalene Dianhydride Bithiophene Copolymers by Direct Arylation Polycondensation and the Latent Pigment Approach" is highlighted on the Cover of ChemPlusChem.

  • Posterprice for D. Adamczak at the 14th International Symposium on Functional pi-Electron Systems in Berlin.

    Her poster "Indaceno-dithiophene Homo- and Copolymers with Asymmetric Side Chains via Direct Arylation Polycondensation" recieved the Thieme posterprice.

  • New Publication in J. Mater. Chem. C. released: Controlling intermolecular redox-doping of naphthalene diimides.

    Schmidt et al. reported about the n-dotation of diverse NDI-derivates with an NDI-attached Amin-sidechain. By Variation of the NDI-coresubstitutents, the radicalanionyield and their airstability can be tuned.

  • New Publication ini ACS Appl. Mater. Interfaces released: Block junction-functionalized all-conjugated donor-acceptor block copolymers.

    Nübling et al. berichten über die Synthese und Charakterisierung von direkt aneinander geknüpften Donor- und Akzeptorpolymeren und zeigen dass ihre Eigenschaften von morphologischen Effekten dominiert werden.

  • New Publication in Eur. J. Org. Chem. released: A Defect-Free Naphthalene Diimide Bithiazole Copolymer via Regioselective Direct Arylation Polycondensation.

    Matsidik et al. berichten über die optimierte Syntheseroute eines neuen NDI-Bithiazol-Copolymers mit hoher Temperaturstabilität und niedrigem LUMO, welches es vor allem auch als organisches Funktionsmaterial interessant macht.

  • New Publication in Adv. Mater. released: Highly sensitive, anisotropic and reversible stress/strain-sensors from mechanochromic nanofiber composites.

    Raisch et al. berichten über die Herstellung orientierter Nanofasern eines mechanochromen Spiropyran-Copolymers. Dies ermöglicht eine richtungsabhängige Farbänderung bei Zug-Dehnung.

  • The 100th publication of the Sommer group on steric and electronic effects of Ni and Pd catalysts with mixed ligands for the Kumada polymerization of a sterically hindered thiophene monomer was just accepted in Polymer Chemistry!

  • New Publication in ACS Appl. Mater. Interfaces released: In Situ Synthesis of Ternary Block Copolymer / Homopolymer Blends for Organic Photovoltaics.

    Nübling et al. berichten über die Synthese und Eigenschaften eines konjugierten Triblock-Copolymers. Phasenverhalten und Solarzellen-Performance werden in Abhängigkeit von Kettenlängen und Annealing-Temperaturen untersucht.

Information about Teaching in Summer Term 2020
The Lectures "Polymermaterialien", "Naturstoffe und Grundlagen der Biochemie" und "Organische Chemie für die Nebenfachausbildung" will be tought via online client, starting at April, 13th. The Documents can be downloaded from our Homepage as usual. There are no current information about online-based Seminars/Excercises, but the Exercise sheets can be downloaded as usual.
