1. Electronic Energy Transfer within Asymmetric Pairs of Fluorophores: Partial Donor-Donor Energy Migration (PDDEM)
Sammanfattning : A kinetic model of electronic energy migration within pairs of photophysically non-identical fluorophores has been developed. The model applies to fluorescent groups that exhibit different photophysical and spectral properties when attached to different positions in a macromolecule. LÄS MER
2. A new approach to the analyses of fluorescence depolarisation experiments in the presence of electronic energy transport
Sammanfattning : A new and general procedure is described for a detailed analysis of time-resolved fluorescence depolarisation data in the presence of electronic energy migration. An isotropic ensemble of bifluorophoric molecules (D1-R-D2) has been studied to demonstrate its utility. LÄS MER
3. Fluorescence studies of complex systems : organisation of biomolecules
Sammanfattning : The homo and hetero dimerisation of two spectroscopically different chromophores were studied, namely: 4,4-difluoro-4-bora-3a,4a-diazas-indacene (g-BODIPY) and its 5-styryl-derivative (r-BODIPY). Various spectroscopic properties of the r-BODIPY in different common solvents were determined. LÄS MER
4. Two-Photon Excited Fluorescence Depolarisation : Experimental and Theoretical Development
Sammanfattning : We have studied fundamental aspects of time-resolved two-photon excited fluorescence depolarisation. The thesis presents experimental as well as theoretical progress. LÄS MER
5. Extended Förster Theory of Electronic Energy Transport within Pairs of Reorienting Chromophoric Molecules
Sammanfattning : An extended Förster theory (EFT), previously derived (L. B.-Å. Johansson et al. LÄS MER
