Oxidation reactions play a crucial role in both environmental and biological systems. Therefore, my thesis started with the study of aryl-substituted benzyl radicals. In the second part of my thesis, the effect of the solvent on H atom abstractions from C-H donors by oxygen-centered radicals. In the last part, I developed a fluorescence-based supramolecular tandem assay to monitor a biologically important oxidation process, namely an enzymatic oxidation. When searching for a macrocyclic receptor (required for tandem assays) for the substrate of peroxidases, namely iodide, I found a novel interaction (halogen bonding) in supramolecular host-guest complexes associated with cucurbiturils, which is based on the encapsulation of molecular iodine inside the nanocavity of CB6.}, language = {en} }
