  2. 1. NMR Investigations of Host-Guest Complexes and Their Dynamic Properties

    Author : Zdenek Tosner; Jozef Kowalewski; Josef Stepanek; Klaus Muller; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; supramolecular chemistry; host-guest complexes; non-covalent interactions; nuclear magnetic resonance; molecular motion; C-13 relaxation; deuterium NMR; dipolar recoupling; Physical chemistry; Fysikalisk kemi;

    Abstract : This thesis discusses several different methods offered by solution and solid state nuclear magnetic resonance for investigation of host-guest complexes and their constituents. The presented methods were used especially (but not exclusively) to address rotational dynamics of the bound guest in different molecular systems. READ MORE

  4. 2. Selectivity in Host-Guest Chemistry

    Author : Gunnar Westman; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis describes host-guest complexes with the use of a biphenyl crown ether or cyclodextrin as host. Complexes between the biphenyl crown ether and salts form phenylalanine esters were studied. READ MORE

  5. 3. Understanding Defect Structures and Host-guest Interactions in Metal-organic Frameworks

    Author : Kang Zhengzhong; Yaoquan Tu; Lars Ojamäe; KTH; []
    Keywords : metal-organic framework; defects; host-guest; molecular dynamics simulation; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Abstract : Metal-organic frameworks (MOFs) represent a class of crystalline porous materials with prospective applications in molecular capture, separation, storage and catalysis. It has been discovered that there exist various structural defects in MOFs, which can have dramatic impact on their properties. READ MORE

  6. 4. Host-Guest Interactions for Structural Analysis of Organic Molecules : Development of new Tools for Stereochemical Characterization

    Author : Sandra Olsson; Adolf Gogoll; Kari Rissanen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metalloporphyrins; host-guest systems; bis-porphyrin tweezers; stiff stilbene macrocycles; organic synthesis; porphyrin binding studies; NMR; ECCD; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : The focus of this thesis is on the development of molecular tweezers as host-guest systems for stereochemical characterization of small organic molecules.There are two central problems to stereochemical characterization of small molecules. READ MORE

  7. 5. Synthesis and Studies of NADH Models: Stereoselective Reductions and Host-Guest Properties

    Author : Ulrik Gran; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; synthesis; NADH model; host-guest complex; stereoselective reductions; macrocyclic; reducing agent;

    Abstract : The aim of the project has been to synthesise macrocyclic NADH models and to study them as reducing agents and hosts. Three types of macrocyclic NADH models have been synthesised. They consist of the same subunits; a chiral unit, a nicotinamide unit and an aromatic spacer. READ MORE
