[a]

Molar absorptivity measurements were carried out in CHCl3 except for BDP740-OH which was performed in EtOH.

[b]

The fluorescence quantum yield was determined in CHCl3 (MeOH for BDP740-OH) at 298 K with Aza BODIPY (Φflu = 0.34).

[c]

SO quantum yields were determined in CHCl3 with [Ru(bipy)3]Cl2 as a reference (ΦΔ = 0.77 in MeOH).

[d]

Not determined under our experimental conditions.

[e]

Brightness (BT = ε × Φflu).

[f]

Phototoxic power (PP = ε × ΦΔ).
