ABSTRACT

Light-harvesting complexes, one of nature's supreme examples of nanoscale engineering, have inspired researchers to construct molecular optical devices, such as photonic wires, which are optimised for efficient transfer of excited-state energy over large distances. The control parameters for the design and the advantages of single-molecule fluorescence spectroscopy for the study of such complex systems are discussed with respect to energy-transfer mechanisms, chromophore selection and arrangement as well as static and dynamic heterogeneity.
