1. Perfluroaryl azides : Reactivities, Unique Reactions and their Applications in the Synthesis of Theranostic Agents
Sammanfattning : The work centersaround perfluoroaryl azides (PFAAs), and theirability to undergo certain fast and robusttransformations. The chemistry was furtherappliedfor biomedical applications.The first section focuses on the azide-aldehyde-amine cycloaddition using PFAAs. LÄS MER
2. Organic Azides : Functional Molecules and Materials
Sammanfattning : The work presented in this thesis stems from the chemistry of the azido group, and more specifically from the unique reactivity of perfluorinated aromatic azides and how to use this reactivity to access new types of molecules to enable new applications in asymmetric synthesis and materials.In the first section of this thesis, a photoactivatable fluorescence probe is presented, where the non-luminescent azide was activated via a UV-light-promoted intramolecular N–H insertion reaction forming a fluorescence emitter.

3. Dynamic Chemistry for Asymmetric Synthesis, Molecular Motion and Constitutional Exchange
Sammanfattning : Living matter is built on complex dynamic systems consisting of numerus biotransformations. By exploiting the adaptive and evolutive behaviors ofmolecular matter, dynamic chemistry has developed as an important tool tounderstand the organization of nonliving matter into complex living systems.

4. Exciton coupling and energy transfer in perylene-based systems
Sammanfattning : Understanding the nature of photoinduced processes in organic molecules is essential for the design and synthesis of compounds with desired photochemical properties. This dissertation aims for gaining knowledge and mechanistic understanding of energy transfer in perylene-based systems. LÄS MER
5. Novel fluorescent tools and techniques for 3D imaging of the cleared brain
Sammanfattning : Background: To better understand the complexity of the brain and how it becomes impaired under different pathological states, a considerably large number of brains would be needed for imaging to generate highly detailed maps in 3D. Chemical probes can offer a readily scalable labelling method that is robust, easy to use with the quick operation, and feasible for human tissue where genetic viral and toxin tracers are inappropriate.
