compound. The wavelength maximum for the observed partially structured low-energy absorption band is relatively insensitive to changes in the solvent polarity and polarizability. TD-DFT calculations predict that the long wavelength absorption envelope originates from localised π–π* transitions with no contribution from an n–π* state. The fluorescence quantum yield and singlet lifetime of the dye in MeCN
