• Hydrogen peroxide

Hydrogen peroxide (H2O2) has been associated as the most important member of reactive oxygen species (ROS) for a long time. Two novel fluorescent probes (P1 and P2) are synthesized and characterized for rapid detection of H2O2. In the presence of base, the probes provide remarkable changes in optical properties with extremely fast response towards H2O2 based on the cleavage of C-O bond and the principle of excited state intramolecular proton transfer (ESIPT) or photo-induced electron transfer (PET).
