A pyrene-based fluorescent probe for highly sensitive and selective detection of hydroxylamine in environmental water samples
In this study, a pyrene-based fluorescent probe (PCPA) was designed, synthesized and developed for the detection of HA. In the presence of HA, PCPA was converted to the oxime derivative (PCO) through a nucleophilic addition–elimination reaction, accompanied by significant enhancement in fluorescence at 408/425 nm.
