Dendrimers coumarin chromophores

Fig. 28 Unsymmetrical dendrimers, containing both mannose binding units and two coumarin chromophores have been prepared on a Bottom scaffold using click chemistry [190]...

The [Ru(bpy)3] + core has more recently been used to construct first-generation dendrimers containing coumarin-450 chromophoric groups. 

Using a similar type of branch, developed by the Frechet group, they have published extensively on chromophore labeled dendrimers [12], The dendrimers possessing coumarin-2 dyes at the periphery, and either coumarin-343 (Fig. 1.4) or a heptathiophene dye at the core, were studied by time-resolved fluorescence and transient absorption spectroscopy. It was revealed that upon excitation of the rim chromophores almost no direct fluorescence occurred from these initially excited chromophores. Instead, only the center...
