   Författare :Magnus Stödeman; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Aqueous Solution; Calixarene; Cyclodextrin; Vaporization; Macrocyclic compounds; Microcalorimetry; Kemi;

   Sammanfattning : The present work involves a microcalorimetric characterization of the interactions among macrocyclic compounds and aliphatic molecules in aqueous solution. The macrocyclic compounds used in the study are a-,b- and g-cyclodextrin and 25,26,27,28-tetrahydroxycalix[4]arene-5,11,17,23- tetrasulphonate. LÄS MER

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

   Författare :Zdenek Tosner; Jozef Kowalewski; Josef Stepanek; Klaus Muller; Stockholms universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER
