摘要：
Nitrite (NO2-) is a common pollutant and is widely present in the environment and in human bodies. The development of a rapid and accurate method for NO2- detection is always a very important task. Herein, we synthesized a partnered excited-state intermolecular proton transfer (ESIPT) fluorophore using the "multi-component one pot" method, and used this as a probe (ESIPT-F) for sensing NO2- ESIPT-F exhibited bimodal emission in different solvents because of the solvent-mediated ESIPT reaction. The addition of NO2- caused an obvious change in colors and tautomeric fluorescence due to the graft ...
