Probing functional (re)organization in photosynthesis by time-resolved fluorescence spectroscopy

The possible mechanisms for reorganisation of outer LHCs of PSII (LHCII) upon state transitions in Chlamydomonas reinhardtii have been discussed for several decades [38, 43-54]. For a long time people adhered to the opinion that upon the transition from state 1 to state 2, 80% of LHCII detaches from PSII and attaches completely to PSI in Chlamydomonas reinhardtii [38, 45]. This thesis provides new insights for the mechanism of state transitions in Chlamydomonas reinhardtii. In the remainder of this thesis, the role of minor light-harvesting complexes in excitation energy transfer to reaction centers of photosystem II are discussed as well as multiexciton dynamics of the alloyed ZnCdTe quantum dots are studied in detail.
