  3. 2. Hydrolytic and oxidative catalytic activities of bio-inspired dinuclear metal complexes

    Författare :Biswanath Das; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bioinorganic Chemistry; Metalloenzymes; Catalyst; Transition states; Phosphoesterase;

    Sammanfattning : A number of homo- and heterodinuclear complexes have been synthesized as structural and functional models for the the active sites of phosphoesterases and soluble methane monooxygenases. The complexes are based on four new dinucleating ligands containing a central, potentially bridging, phenolate moiety. LÄS MER

  4. 3. Mononuclear Ruthenium Complexes that Catalyze Water to Dioxgen Oxidation

    Författare :Lianpeng Tong; Licheng Sun; Randolph Thummel; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ruthenium complex; Homogeneous catalysis; Water oxidation; O2 evolution; anionic ligand; Molecular catalyst; Electrocatalysis; Kinetics; Artificial photosynthesis; Light-driven; Immobilization of catalyst;

    Sammanfattning : The theme of this thesis is the development of mononuclear Ru-based complexes that are capable of catalyzing the water oxidation (or O2-evolving) reaction, e.g. 2 H2O → O2 + 4 H+ + 4 e−. Several families of mononuclear Ru water oxidation catalysts were designed and prepared. LÄS MER

  5. 4. Iron, Manganese and Iridium Complexes From Models of RNR and Catalase to Water Oxidation

    Författare :Michele Bedin; Anders Dr. Thapper; Sascha Prof. Ott; Vadim G. Kessler; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Iron; manganese; MnCAT; RNR; biomimetic; Kemi; Chemistry;

    Sammanfattning : The focus of this thesis has been synthesise and study metal complexes that mimic the structure and function of the active site in two particular metalloenzymes, ribonucleotide reductase (RNR) and manganese catalase (MnCAT). These two metalloenzymes both have two transition metals ions in the cofactor: two manganese ions in MnCAT and either two iron, iron-manganese or two manganese ions in RNR. LÄS MER
