Abstract

In recent years the excessive use of hydrazine containing chemical pesticides and insecticides in farming practices is well pronounced, which directly or indirectly impart a great threat towards the total environment. Considering the above fact we are motivated to introduce a new, efficient and simple chemodosimeter (NCD) based on a carbazole-naphthalimide framework to recognize and estimate the mutagenic hydrazine within several affected cropland flowers. Probe NCD can detect hydrazine in a nanomolar range (65 nM or 2 ppb) in the presence of other metal ions, anions and amines, which gives it not only great potential but also makes it selective and sensitive. The sensing mechanism is confirmed by UV-vis, emission, and mass spectroscopy, and computational studies. We have successfully characterized probe NCD by 1H and 13C NMR and mass spectrometry as well as by single crystal analysis.
