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

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

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

5. Light-Triggered Conformational Switches for Modulation of Molecular Recognition : Applications for Peptidomimetics and Supramolecular Systems
Abstract : The main focus of this thesis is on photochemical modulation of molecular recognition in various host-guest systems. This involves the design, synthesis and integration of light-triggered conformational switches into peptidomimetic guests and molecular tweezer hosts. READ MORE
