A novel ratiometric fluorescent probe for selective detection and imaging of H2S

In this work, a novel phenoxazine-based fluorescent probe BPO-N3 was developed to detect H2S. The results showed that the probe had high selectivity and sensitivity toward H2S, and its detection mechanism was based the ratio between green and red fluorescence signals; its detection limit was as low as 30 nM. The fluorescent imaging experiments further showed that the probe BPO-N3 could successfully detect endogenous and exogenous H2S in living cells. This probe can be used as a powerful tool for in-depth study of H2S function in various physiological processes.

Phototransformation of resorcinol induced by excitation of nitrite and nitrate ions. I: nitrite ions

The excitation of nitrite ions in the presence of resorcinol (I) leads to the formation of 4-nitrosoresorcinol (II) as the major photoproduct. The reaction is inhibited by formate ions. In the absence of formate ions, the transformation is not affected by the presence of oxygen. From the influence of oxygen and formate ions, it is concluded that the formation of II results from a reaction of I with N2O3. Dinitrogen trioxide is formed by oxidation of nitrite ions by hydroxyl radicals resulting from the photolysis of nitrite ions.
