3. Synthesis of Covalently Linked Diporphyrins: Model Compounds for Intramolecular Energy and Electron Transfer
Sammanfattning : Three series of donor-bridge-acceptor compounds have been synthesized to probe the influence of various bridge chromophores on energy and electron transfer. The donor-bridge-acceptor compounds in each series comprise two different porphyrins, acting as donor and acceptor, covalently linked by bridge chromophores. LÄS MER
4. Towards the Development of Photoswitchable β-Hairpin Mimetics
Sammanfattning : Peptide secondary structure mimetics are important tools in medicinal chemistry, as they provide analogues of endogeneous peptides with new physicochemical and pharmacological properties. The β-hairpin motif has been shown to be involved in numerous physiological processes, among others in regulation of eucariotic gene transcription. LÄS MER
5. Supported Mono- and Bimetallic Gold Nanoparticle Catalysts for Different Organic Transformations
Sammanfattning : Supported gold nanoparticles are emerging as an important class of catalysts for various organic transformations due to their tunable properties. This thesis embraces the fundamental studies of supported gold nanoparticles for different organic reactions from the viewpoint of understanding the role of synthesis methods, nature of carriers, and addition of second metal on the properties and functions of gold catalysts.
