  1. 1. Creating Optical Activity: Total Spontaneous Resolution and Viedma Ripening

    Författare :Per Martin Björemark; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optical activity; absolute asymmetric synthesis; total spontaneous resolution; Viedma ripening; grinding; chirality; conglomerate; coordination compound; coordination polymer; single crystal X-ray diffraction; solvent free oxidation; nantioselective sulfide oxidation; solid state VCD;

    Sammanfattning : The creation of optical activity has been considered as something impossible even though reports of such creation via total spontaneous resolution since the 1940´s have been published. More recently Viedma ripening have been developed that also produce enantiopure bulk product. Both methods are examples of absolute asymmetric synthesis i.e. LÄS MER

  4. 3. Metal Organic Frameworks: History, Synthesis, and Topological approach

    Författare :Cédric Borel; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MOF; crystal structures; crystal engineering; network; coordination chemistry; synthesis; TOPOS; systre; gas storage;

    Sammanfattning : The storage, separation, purification and catalytic reactions of small molecules are important research domains in both pure and applied chemistry, where porous materials play a major role. Among the different possible options for the preparation porous materials a recent approach is to build structures based on metal ions, metal complexes, or metal clusters, bridged by organic ligands.

  5. 4. Modification of microcapsules for controlled release

    Författare :Markus Andersson Trojer; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; block copolymer; coordination chemistry; polyelectrolyte multilayer; cross-linking; vibrational spectroscopy; electron paramagnetic resonance; imidazole; controlled release; colloidal stability; Microcapsule; quartz crystal microbalance with dissipation;

    Sammanfattning : Fouling of marine organisms such as algae and barnacles on the boat hull is an enormous problem for the shipping industry. The negative consequences for the society are both economical and environmental. To prevent fouling in general, biocides are typically incorporated directly into the paint. LÄS MER

  7. 5. Coordination of Phosphine-Thioether Ligands to Low-valent Metal Centers

    Författare :Roger Persson; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polynuclear metal complexes; fluxional behavior; cluster; thioether; phosphine; crystal structure; sulfur; triosmium;

    Sammanfattning : The reactivity of the phosphine-thioether ligands bis(2-diphenylphosphino) ethylthio)ethane (PSSP), bis(2-(diphenylphosphino) ethyl)sulfane (PSP), PPh2CH2CH2SMe (PS), PPh2(o-C6H4SMe (PortoS), and PPh(o-C6H4SMe)2 (PSS) towards low-valent carbonyl clusters has been studied. In all structurally characterized clusters, the ligand donor atoms are terminally coordinated. LÄS MER
