 | Lupton, John Mark | Ultrafast intramolecular energy transfer in single conjugated polymer chains probed by polarized single chromophore spectroscopy | Single molecule spectroscopy of rigid-rod ladder-type conjugated polymers reveals individual chromophore units on a polymer chain, exhibiting fluorescence linewidths of less than 1 nm. Whereas the fluorescence from a single chromophore is fully linearly polarized at low temperatures, a number of exc... | Single molecule spectroscopy; Intramolecular energy transfer; Chromophore spectroscopy; Chromophores; Rigid-rod; Ladder-type | 2004 |
