Functionally layered dendrimers: a new building block and its application to the synthesis of multichromophoric light-harvesting systems

Org Lett. 2005 Sep 29;7(20):4451-4. doi: 10.1021/ol0516824.

Abstract

[reaction: see text] A divergent synthesis of internally functionalized dendrimers based on a modular functional monomer has been developed. This strategy was applied to the construction of a light-harvesting dendrimer containing one set of naphthopyranone dyes located at the interior and another set of coumarin chromophores located in the adjacent outer layer surrounding a porphyrin acceptor. Quantitative energy transfer from both donor pigments is observed, giving rise to exclusive emission from the porphyrin core over all excitation wavelengths.
