The syntheses of novel rigid dendritic ligands and their ruthenium complexe
s, in which 1,3,5-phenylene-based hydrocarbon dendron units were directly c
onnected to a phenanthroline ligand at the 3 and 8 positions, are described
. Preliminary absorption and fluorescence results are indicative of highly
efficient energy transfer within the rigid metallodendrimers. (C) 2000 Else
