11. -1 to account for the red shift observed in the vibrationless electronic excitation energy when the chromophore is part of the nanostar. Using the shifted absorption spectrum of the free monomer represents a rough approximation to the absorption corresponding to the 3-ring chromophore in the nanostar. No change is expected in the fluorescence emission of the donor because the model used (structure 9 in ref 4) has the same periphery composition as the nanostar.
