  2. 1. Ruthenium(II) Polypyridyl Complexes : Applications in Artificial Photosynthesis

    Author : Olof Johansson; Licheng Sun; Björn Åkermark; Michael D Ward; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Chemistry; Kemi;

    Abstract : Molecular mimics of PS II, which consist of a photosensitizer linked to electron acceptors/donors, are attractive candidates for the conversion of solar energy into chemical energy. Several different classes of sensitizers have been studied and among these, ruthenium(II) polypyridyl complexes continue to attract major attention. READ MORE

  4. 2. Tuning of the Excited State Properties of Ruthenium(II)-Polypyridyl Complexes

    Author : Maria Abrahamsson; Leif Hammarström; Hans-Christian Becker; Russell Schmehl; Uppsala universitet; []
    Keywords : Physical chemistry; Artificial photosynthesis; Ruthenium II ; Bistridentate complexes; Excited state lifetime; Linear donor-photosenstizer-acceptor arrays; Temperature dependence; Excited state decay; Fysikalisk kemi;

    Abstract : Processes where a molecule absorbs visible light and then converts the solar energy into chemical energy are important in many biological systems, such as photosynthesis and also in many technical applications e.g. photovoltaics. READ MORE

  5. 3. Beyond Classical Ruthenium(II) Polypyridyl Complexes : Photosensitizers as Building Blocks For Linear Donor-Photosensitizer-Acceptor Assemblies

    Author : Michael Jäger; Olof Johansson; Edwin Constable; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi;

    Abstract : This thesis describes ruthenium(II) polypyridyl-type complexes tailored for artificial photosynthesis. Inspired by Nature, the primary events in photosystem II are mimicked by donor-photosensitizer-acceptor (D-P-A) assemblies. READ MORE

  6. 4. DNA Interaction Dynamics of Ruthenium(II) Complexes

    Author : Fredrik Westerlund; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fluorescence; ruthenium; polarized spectroscopy; threading; sequence selectivity; photophysics; binding kinetics; DNA; intercalation;

    Abstract : DNA-binding of small synthetic ligands is of great importance in a number of different applications, from medicine to molecular biology. This thesis focuses on interactions between DNA and ruthenium(II) complexes, in particular the dimers [µ-bidppz(L)4Ru2]4+ (L=1,10-phenanthroline (P) or L=2,2-bipyridine (B)). READ MORE

  7. 5. Ruthenium(II) Polypyridyl Complexes in Supramolecular Systems relevant to Artificial Photosynthesis

    Author : Henriette Wolpher; Björn Åkermark; Licheng Sun; Johannes Vos; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ruthenium complexes; Organic chemistry; Organisk kemi;

    Abstract : This thesis describes the synthesis and properties of ruthenium complexes relevant to artificial photosynthesis. The work includes preparation of RuIIpolypyridine complexes as well as multi component systems where RuII(bpy)3 or RuII(tpy)2 type complexes are used as photosesnsitizers. READ MORE
