Absorption maximum.
Fluorescence emission maximum (obtained by exciting at the absorption maximum of the dye).
Extinction coefficient at absorption maximum.
Fluorescence quantum yield calculated by a standard relative method using Bodipy-CO2H, (ϕ = 0.57 in CH2Cl2), rhodamine B (ϕ = 0.70 in CH3OH), and zinc tert-butyl phthalocyanine (ϕ = 0.37 in benzene).
