Description
Summary:The synthesis and photophysical characterization of a generation 1 dendrimer containing four coumarin 2 laser dyes at the periphery and a perylenebis(dicarboximide) derivative at the core are described. It was found that 99% of the UV light absorbed by the peripheral coumarin 2 donor chromophores is transferred through fluorescence resonance energy transfer (FRET) to the core acceptor. Emission from the core via FRET is observed in the near-infrared with a 6.2-fold amplification relative to direct excitation.
