Representative spectra showing photoinduced degradation of 50 μM N¹-(anthracen-9-ylmethyl)ethane-1,2-diaminium dichloride 2 in the presence and absence of 400 mM of chloride salts in 10 mM sodium phosphate buffer pH 7.0. Samples were irradiated at 350 nm for time intervals from: (A, B) 0 to 180 s and (C, D) 0 to 5 min in a ventilated Rayonet photochemical reactor fitted with 8 RPR-3500 Å, 24 W lamps.
