Zwei Arten der Emission bei einer einzigen Anregungswellenlänge wurden von S. V. Eliseeva, S. Petoud et al. für ein mehrkerniges SmIII‐Polyamidoamin‐basiertes Dendrimer gefunden. In ihrer Zuschrift auf S. 2971 ff. demonstrieren die Autoren, dass es im sichtbaren und im Nah‐IR‐Bereich emittiert. Das Dendrimer ist zellgängig und nicht cytotoxisch und zeigte sich in einem Lebendzell‐Imaging‐Experiment...
We report herein the synthesis of a luminescent polynuclear dendritic structure (SmIII‐G3P‐2,3Nap) in which eight SmIII ions are sensitized by thirty‐two 2,3‐naphthalimide chromophores. Upon a single excitation wavelength, the dendrimer complex exhibits two types of emission in the visible and in the near‐infrared (NIR) ranges. SmIII‐G3P‐2,3Nap was non‐cytotoxic after 24 h of incubation and up to...
