For more than 150 years, since the synthesis of urea by Friedrich Wöhler in 1828, molecular chemistry has developed a vast array of highly sophisticated and powerful methods for the construction of more complex molecular structures. Beyond the molecular chemistry based on the covalent bond, there lies the field of supramolecular chemistry, aims to gain control over the intermolecular bond. Supramolecular species are characterized both by the spatial arrangement of their components and by the nature of the intermolecular bonds that hold these components together. They possess well-defined structural, conformational, thermodynamic and kinetic properties. Research has been focused on utilization of such confined spaces to manipulate reaction dynamics, properties of the encapsulated guest molecules. This research presented in this thesis is a consolidated account of photophysical and photochemical reactions carried in water-soluble macrocycles, cavitands and dynamic host systems such as dendrimers and micelles. With the aid of NMR (1D and 2D) spectroscopic techniques, the host-guest complex characterization is executed.
