Selective reaction with NO provides fluorescent nitroxide radicals 2 from nonfluorescent o ‐quinodimethane derivatives of type 1 as a result of rearomatization. Intentional reduction of 2 to nonradical products with the intact fluorophore results in a strong increase in fluorescence intensity. The detection of low levels of nitric oxide, especially in biological systems, is thus possible.
