^aAbsorption and fluorescence data measured using methanol.

^bFluorescence quantum yields were determined using rhodamine 6G in methanol as the standard (Φ_f = 0.94)⁴².

^cSinglet oxygen quantum yields were determined by the DPBF bleaching method, using HP in ethanol as a reference (Φ_Δ = 0.53)⁴³.
