2. 1. Perfluroaryl azides : Reactivities, Unique Reactions and their Applications in the Synthesis of Theranostic Agents

   Author : Sheng Xie; Mingdi Yan; Olof Ramström; Stefan Bräse; KTH; []
   Keywords : Click Chemistry; Dipolar Cycloaddition; Enamine; Triazoline; Amidine; Aggregation-induced emission; pure nanodrugs; aryl amide; thioacid azide reaction; nucleophilic aromatic substitution; azide-masked fluorophore; nitrene insertion; Kemi; Chemistry;

   Abstract : 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. READ MORE

4. 2. Organic Azides : Functional Molecules and Materials

   Author : Giampiero Proietti; Peter Dinér; Per I. Arvidsson; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; perfluorinated Aromatic Azide; Photoactivatable; fluorophores; aggregation-induced emission; sulfonimidamides; sulfoximes; chiral auxilary; organogel; azides reduction; Ni-B; Kemi; Chemistry;

   Abstract : 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.

6. 4. Exciton coupling and energy transfer in perylene-based systems

   Author : Alexei Cravcenco; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic Chemistry; Photophysics; Energy transfer; FRET; Perylene; J-aggregate;

   Abstract : 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. READ MORE

7. 5. Novel fluorescent tools and techniques for 3D imaging of the cleared brain

   Author : Alex Yu Hin Wong; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : 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.
