  1. 1. Nickel and iridium pincer complexes with saturated frameworks - synthesis and reactivity

    Författare :Klara Jonasson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PCP complexes; aliphatic pincer ligands; coordination; cyclometallation; iridium; nickel; organometallic synthesis; CO2 activation; catalysis;

    Sammanfattning : As the tridentate chelate complexes referred to as pincer complexes have expanded their scope as homogeneous catalysts, there is an increased interest in electronic and steric fine-tuning of such complexes. One accessible variable in this aspect is the hybridisation of any coordinated carbon atoms. LÄS MER

  3. 2. Homoleptic Arylcopper Complexes

    Författare :Henrik Eriksson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cocrystallisation; Grignard; organocopper; bromide; thienyl; mesityl; crystal structure; synthesis; copper I ; arylcopper;

    Sammanfattning : New arylcopper complexes have been synthesised and characterised structurally. The reaction between the Grignard reagent (viph)MgBr (viph = ortho-vinylphenyl) and CuCl has been studied and two unstable mixed aryl/halide intermediates, [Mg(THF)6][Cu5(viph)2Br4]2.THF and [Mg(THF)5Cl][Cu5(viph)4Br2].

  4. 3. A molecular guide to efficient charge transport : Coordination materials for photovoltaic cells

    Författare :Hannes Michaels; Marina Freitag; Aldo Di Carlo; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coordination chemistry; energy conversion; photovoltaics; charge transport;

    Sammanfattning : Emerging solar energy conversion and energy storage technologies play a vital role in solving the present energy crisis and achieving carbon net zero. Currently, they are limited by the use of inefficient, unstable and expensive charge transport materials. LÄS MER

  5. 4. Modeling Photofunctional Transition Metal Complexes

    Sammanfattning : Transition metal complexes play a crucial role in solar energy conversion. These coordination compounds have promising applications in dye-sensitized solar cells and photocatalysis, with particular interest in solar fuel production. LÄS MER

  7. 5. Mimicking the Outer Coordination Sphere in [FeFe]-Hydrogenase Active Site Models : From Extended Ligand Design to Metal-Organic Frameworks

    Författare :Sonja Pullen; Sascha Ott; Patrick L. Holland; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; [FeFe]-hydrogenases; outer coordination sphere; model complexes; biomimetic catalysis; artificial photosynthesis; metal-organic frameworks;

    Sammanfattning : Biomimetic catalysis is an important research field, as a better understanding of nature´s powerful toolbox for the conversion of molecules can lead to technological progress. [FeFe]-hydrogenases are very efficient catalysts for hydrogen production. These enzymes play a crucial role in the metabolism of green algae and certain cyanobacteria. LÄS MER
