An interior of 18 amide groups and a periphery functionalized with 24 dansyl groups forms a light-harvesting dendrimer which features intense absorption bands in the near-UV spectral region and a strong fluorescence band in the visible region. Upon encapsulation of Nd3+ ions, the fluorescence of the dansyl groups is quenched and an intense sensitized near-infrared emission of Nd3+ is observed. The associated energy transfer is shown in the cartoon.

Abstract
An interior of 18 amide groups and a periphery functionalized with 24 dansyl groups forms a light-harvesting dendrimer which features intense absorption bands in the near-UV spectral region and a strong fluorescence band in the visible region. Upon encapsulation of Nd3+ ions, the fluorescence of the dansyl groups is quenched and an intense sensitized near-infrared emission of Nd3+ is observed. The associated energy transfer is shown in the cartoon.File in questo prodotto:
