  2. 1. Chirality in Crystal Engineering

    Author : Krister Larsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; networks; 2; coordination chemistry; crystal engineering; 10; 3-nets; hydrogen bonding; 2 -biimidazole; single crystal X-ray diffraction; bis-chelating ligands; chirality;

    Abstract : Crystal engineering combines supramolecular chemistry with solid state chemistry. The goal is to make molecular entities assemble into predefined structures with specific properties. At the same time much research is focused on the understanding of the intermolecular interactions governing the crystallisation process. READ MORE

  4. 2. Activation of CO2 by Palladium Complexes Bearing Tridentate PCP Ligands

    Author : Roger Johansson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metallorganisk kemi; Organometallic chemistry; Kinetics; Insertion reactions; PCP ligands; CO2 activation; Palladium II complexes;

    Abstract : The present thesis deals with the activation of CO2 by insertion reactions into palladium-carbon bonds. This has been realised for the complexes {2,6-bis[(di-t-butylphosphino)methyl]benzene}palladium(II)methyl [(PCP)PdMe] and (PCP)PdCH2CHCH2. These complexes have also been used in the catalytic carboxylation of ZnMe2 and Bu3SnCH2CHCH2. READ MORE

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

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

    Abstract : 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.
