title: Fluorescence spectroscopy of single photosynthetic light-harvesting supramolecular systems.
abstract: Recent spectroscopic studies of photosynthetic light-harvesting supramolecular complexes at the single supramolecule level are reviewed. This report describes the "single-molecule" investigation on light-harvesting complex 2 (LH2) of purple photosynthetic bacteria, phycobiliproteins of cyanobacteria and red algae, light-harvesting complex 2 (LHC2) of higher plants, and chlorosomes of green photosynthetic bacteria. Unique behaviors and spectral features of single light-harvesting apparatus have been unraveled that were hidden by the ensemble averaging of many of the complexes. The information obtained will be useful for understanding the electronic structures and energy-transfer mechanism of photosynthetic light-harvesting supramolecular systems.
