Controlled Photochemical Release of Nitric Oxide from O2-Naphthylmethyl- and O2-Naphthylallyl-Substituted Diazeniumdiolates

Abstract

The photochemistry of O2-naphthylmethyl- and O2-naphthylallyl-substituted diazeniumdiolates has been investigated. Electron-donating methoxy group substitution is shown to have a significant effect on the observed photochemistry, with the appropriate substitution pattern resulting in efficient diazeniumdiolate photorelease. Observed nitric oxide release rates from these photoprecursors are consistent with those expected for normal thermal dissociation of the diazeniumdiolate in aqueous solutions and show the same pH dependence.
