Significance
A reactivity-based probe for the detection of nitrating agents is described. Probe molecule 1 is nonfluorescent due to efficient photoinduced electron transfer from the electron-rich phenol substituent to the electron-deficient dicyano-BODIPY ring system. Upon exposure to nitrosonium tetrafluoroborate or peroxynitrite in aqueous solution, the phenol ring undergoes rapid nitration. The resulting decrease in electron density suppresses photoinduced electron-transfer, and thus the nitration product 2 is highly fluorescent.
