  2. 1. Quantum Coherence for Light Harvesting

    Author : David Palecek; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coherent two-dimensional spectroscopy; Quantum coherence; Light harvesting; Photosynthetic reaction center; Energy transfer;

    Abstract : Almost all life on Earth depends on the products of photosynthesis — the biochemical process whereby solar energy is stored as chemical-rich compounds. The energy of captured photons is transferred through a network of pigment-protein complexes towards the reaction center. READ MORE

  5. 3. Excited States of Carotenoids and Their Functions in Light Harvesting

    Author : Donatas Zigmantas; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spektroskopi; magnetic and optical properties; Carotenoids; light-harvesting; excited states; excitation energy transfer; femtosecond spectroscopy; supraconductors; magnetic resonance; electrical; Condensed matter:electronic structure; time-resolved fluorescence spectroscopy; magnetisk resonans; supraledare; magnetiska och optiska ; egenskaper elektriska; Kondenserade materiens egenskaper:elektronstruktur; relaxation; spectroscopy;

    Abstract : The research presented in this thesis is focused on characterization of photophysical properties of lowest singlet excited states of carotenoids and their functions in the process of photosynthetic light harvesting. It is shown that the various light-harvesting complexes utilize different strategies to achieve efficient energy transfer from carotenoids to (bacterio)chlorophylls. READ MORE

  6. 4. Development of Novel Hydroporphyrins for Light Harvesting and Sensitising NIR Lanthanide Luminescence

    Author : Ruisheng Xiong; Eszter Borbas; Christian Brückner; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chlorin; hydroporphyrin; chlorophyll analogues; light harvesting; lanthanide luminescence; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : Chlorins, as the core structures of chlorophylls, have been extensively studied for harvesting solar energy, fluorescent imaging and photodynamic therapy against cancer. This thesis is concerned with design and synthesis of novel chlorins as antennae for harvesting light and sensitising near infrared lanthanide luminescence. READ MORE

  7. 5. Multidimensional Fluorescence Polarization Imaging of Single Light Harvesting Complexes

    Author : Sumera Tubasum; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Light Harvesting Complexes; Single Molecule Spectroscopy; Polarization Spectroscopy; Exciton Dynamics; Spectral Disorder;

    Abstract : This thesis presents my research journey in the Department of Chemical Physics,Lund University. Multidimensional fluorescence polarization imaging is used to study single LH2s. The method uses linearly polarized excitation light and the emission is detected through a polarizer. READ MORE
