  2. 1. Polarization portraits of lightharvesting antennas: from single molecule spectroscopy to imaging

    Author : Rafael Camacho Dejay; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Energy transfer; Single molecule spectroscopy; Exciton; Fluorescence microscopy; Fluorescence polarization; Light-harvesting; Chromophore; Conjugated Polymer; Photosynthesis;

    Abstract : Multichromophoric systems are very important in photosynthesis and any device that uses solar energy for its operation. This is because multichromophoric light-harvesting antennas are responsible for the absorption of light and the efficient transfer of the absorbed energy toward distinct places where it is to be used or stored.

  5. 3. Nanoscale organization of luminescent materials and their polarization properties investigated by two-dimensional polarization imaging

    Author : Juanzi Shi; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Semiconductor materials (e.g., conjugated polymers, metal halide perovskites) have been widely used in solar cells, light-emitting diodes, and photodetectors. Organic conjugated systems have high mechanical flexibility and low costs for production. READ MORE

  6. 4. Photoswitchable Peptidomimetics : Synthesis and Photomodulation of Functional Peptides

    Author : Miranda Varedian; Adolf Gogoll; Morten Grøtli; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; β-hairpin; peptidomimetics; stilbene; thioaurone; photochemistry; Organic chemistry; Organisk kemi;

    Abstract : The secondary structure of peptides is of pivotal importance for their biological function. The introduction of photoswitchable moieties into the backbones of peptides provides a unique way of regulating their conformation using an external stimulus, i.e., light. READ MORE
