A series of metallodendrimers 9 – 11 , as well as their corresponding ligands, were designed and synthesized. These materials integrate perylene as a functional core with termini; both chromophores are known for their photovoltaic properties. The products were fully characterized by a combination of 1 H NMR and 13 C NMR spectroscopy, COSY, and MS. Their photophysical properties revealed a broad absorption spectrum with enhanced molar absorption coefficients corresponding to the increase in the number of units, which is indicative of their potential as candidates for light harvesting.
