Release of nitric oxide from a sol-gel hybrid material containing a photoactive manganese nitrosyl upon illumination with visible light.

A polyurethane-coated sol-gel material containing the photoactive Mn nitrosyl [Mn(PaPy3)(NO)]ClO4 rapidly releases NO with high quantum efficiency when exposed to visible light of low intensity. This rigid and strongly colored hybrid material is a convenient point source of NO that can only be triggered with light. Successful delivery of NO to biological targets, such as proteins, by this material has also been demonstrated.
