Hydrazine exposure: A near-infrared ICT-based fluorescent probe and its application in bioimaging and sewage analysis.

Hydrazine (NH) is an environment pollutant with high acute toxicity and potential carcinogenicity, and detection of NH has attracted increasing attention. In the present study, a low toxicity near-infrared fluorescent probe (DCDB) based on the intramolecular charge transfer (ICT) principle was developed. The probe DCDB exhibits excellent selectivity and high sensitivity (LOD = 1.
