Colorimetric and fluorescent detection of hydrazine with high sensitivity and excellent selectivity

It is critical to develop probes for rapid, selective, and sensitive detection of the highly toxic hydrazine in both environmental and biological science. In this work, under mild condition, a novel colorimetric and off-on fluorescent probe was synthesized for rapid recognition of hydrazine with excellent selectivity over other various species including some biological species, metal ions and anions. The limit of quantification (LOQ) value was 1.5×10^-4M-3.2×10^-3M (colorimetric method) and 1.5×10^-4M-3.2×10^-3M (fluorescent method) with as low as detection limit of 46.2μM.
