Abstract(summary):

Abstract Hydrazine is highly toxic to humans and animals when inhaled or in contact with the skin. It is also a very important chemical used as propellant, metal corrosion inhibitor, pharmaceutical and intermediate. The simple detection of hydrazine in solution and biosystems becomes very important as a consequence of the foregoing applications. Herein, we report a two-photon fluorescent probing method using a NIR fluorescent chemodosimeter, displaying turn-on fluorescence and color change after cleaving an O -acetyl moiety by hydrazine, which exhibits good selectivity and sensitively in solution and living cells. Graphical abstract Image 1 Highlights • A two-photo fluorescent method with a chemdosimeter for hydrazine is developed. • The chemdosimeter show a turn-on fluorescent property and color change for hydrazine. • The chemdosimeter could image hydrazine in living cells by two-photon microscopy. • Filter paper coated with the chemdosimeter could detect hydrazine in solution.
