7. Synthesis of Substituted Alkanethiols Intended for Protein Immobilization : Chelate Associated Photochemistry (CAP)
Abstract : The first and main part of this thesis is focused on the design and synthesis of photo-activableand metal chelating alkanethiols. Chelate associated photochemistry (CAP) is a novel conceptof combining two well-known protein (ligand) immobilization strategies to obtain a sensorsurface of covalently bound ligand with defined orientation.

8. Computational chemistry studies of UV induced processes in human skin
Abstract : This thesis presents and uses the techniques of computational chemistry to explore two different processes induced in human skin by ultraviolet light. The first is the transformation of urocanic acid into a immunosuppressing agent, and the other is the enzymatic action of the 8-oxoguanine glycosylase enzyme. READ MORE

9. Influence of Aromaticity on Excited State Structure, Reactivity and Properties
Abstract : This thesis describes work that could help development of new photochemical reactions and light-absorbing materials. Focus is on the chemical concept "aromaticity" which is a proven conceptual tool in developing thermal chemical reactions. It is here shown that aromaticity is also valuable for photochemistry.
