An eosin molecule encapsulated into the dendrimer shown in the picture collects electronic energy from all 64 chromophoric units of the dendrimer, which comprises three different types of chromophore. Efficient intramolecular (within the dendrimer) and intermolecular (dendrimer-host→eosin-guest) energy-transfer processes by a Förster type mechanism, as suggested by the strong overlap between the emission and absorption spectra of the relevant donor and acceptor units.

Abstract

Efficient intramolecular (within the dendrimer) and intermolecular (dendrimer-host→eosin-guest) energy-transfer processes by a Förster type mechanism, as suggested by the strong overlap between the emission and absorption spectra of the relevant donor and acceptor units.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
