摘要：

The excited triplet state of N,N'-dimethyl-N,N'-dinitroso-p-phenylenediamine (BNN3, lambda(max): 299 nm), caged nitric oxide (E-T: 230 kJ mol(-1)), was found to readily undergo N-N bond homolysis to release NO. This suggests that by covalently binding a triplet sensitizing chromophore, e.g., biacetyl, to BNN3 N-methyl group, its NO photoreleasing light can be switched from UV to visible, less cytotoxic light, such as 425 Mm.
