a Absorption values were determined in tetrahydrofuran and fluorescence values were determined in toluene. For a complete description of the methods used, see the Experimental Section; λmax,abs: wavelength of maximum absorption; ε: Molar absorption coefficient; λmax,em: Peak fluorescence wavelength; ФF: Fluorescence quantum yield; ФΔ: Singlet oxygen quantum yield.
