^[a]For BODIPYs 1a,b, 6c, 7a, 7c, 11, 12, 14, and 15 the calculation of fluorescence quantum yield used rhodamine 6G in ethanol (0.95) as standard; for BODIPYs 6a, 7b, and 17, rhodamine B in ethanol (0.49) was used as a standard; for BODIPYs 6b, 8–10, 13, and 16, crystal violet perchlorate in methanol (0.54) was used as standard.
