First Generation Light-Harvesting Dendrimers with a [Ru(bpy)3]2+ Core and Aryl Ether Ligands Functionalized with Coumarin 450

Abstract

A new class of light-harvesting dendrimers based on metal–organic hybrids (see picture) is described, including the synthesis and photophysical characterization. The inorganic core displays sensitized emission with decay times on the microsecond timescale, which is beneficial for fluorescence lifetime-based technologies.
