(Institute for Nanotechnology (Enschede, Països Baixos))
The exciton wave function of a trichromophoric system is investigated by means of single molecule spectroscopy at room temperature. Individual trimers exhibit superradiance and loss of vibronic structure in emission spectrum, features proving exciton delocalization. [...]

(Institute for Nanotechnology (Enschede, Països Baixos)) ; van Hulst, Niek F.. (Institute for Nanotechnology (Enschede, Països Baixos))
We report the first experimental study of individual molecules with femtosecond time resolution using a novel ultrafast single-molecule pump-probe method. A wide range of relaxation times from below 100 up to 400 fs is found, revealing energy redistribution over different vibrational modes and phonon coupling to the nanoenvironment. [...]

4 p, 224.2 KB Effect of disorder on ultrafast exciton dynamics probed by single molecule spectroscopy / Hernando Campos, Jordi (Universitat Autònoma de Barcelona. Departament de Química) ; van Dijk, Erik M. H. P. (Institute for Nanotechnology (Enschede, Països Baixos)) ; Hoogenboom, Jacob P. (Institute for Nanotechnology (Enschede, Països Baixos)) ; García López, Juan José (Institute for Nanotechnology (Enschede, Països Baixos)) ; Reinhoudt, David N. (Institute for Nanotechnology (Enschede, Països Baixos)) ; Crego Calama, Mercedes (Institute for Nanotechnology (Enschede, Països Baixos)) ; García Parajó, María F.. (Institució Catalana de Recerca i Estudis Avançats) ; van Hulst, Niek F.. (Institut de Ciències Fotòniques)
We present a single-molecule study unraveling the effect of static disorder on the vibrational-assisted ultrafast exciton dynamics in multichromophoric systems. For every single complex, we probe the initial exciton relaxation process by an ultrafast pump-probe approach and the coupling to vibrational modes by emission spectra, while fluorescence lifetime analysis measures the amount of static disorder.
