1. NMR Investigations of Host-Guest Complexes and Their Dynamic Properties
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
2. Host-Guest Interactions for Structural Analysis of Organic Molecules : Development of new Tools for Stereochemical Characterization
Sammanfattning : 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. LÄS MER
3. Bicyclo[3.3.1]nonanes as Scaffolds in Supramolecular Chemistry : From Host-Guest Systems to Hydrogen-Bonded Aggregates
Sammanfattning : This thesis describes the use of bicyclo[3.3.1]nonane and its heteroanalogue 1,5- diazabicyclo[3.3. LÄS MER
4. Accurate Force Fields for Spectroscopic Studies of Protein–Ligand Interactions and Self-Assembly Structures
Sammanfattning : The computational prediction of complex molecular behaviors is an essen- tial component of modern chemistry, as it provides a faster and more cost- effective way to explore molecular interactions that may be difficult or even impossible to study experimentally. Molecular dynamics (MD) simulations of- ten serve as a valuable tool for such predictions; however, their accuracy is inherently dependent on the force field (FF) parameters employed. LÄS MER
5. NMR Diffusion Studies of Association in Surfactant Systems Inclusion Complexes, Micellar Solutions and Microemulsions
Sammanfattning : The aim of this thesis has been to investigate self-diffusion behavior of host-guest complex, microemulsion and polymer solution. Pulsed Field Gradient NMR (PFG-NMR) was shown to provide detailed molecular information in all system studied. LÄS MER
