Abstract	A rhodamine B-based fluorescent probe for nitrite ion (NO2 −) has been designed, synthesized, characterized and its properties for recognition of NO2 − were studied. Nearly non fluorescent probe upon reaction with nitrite ion significantly triggered the fluorescence. Fluorescence response is based on ring opening of the spirolactam of rhodamine B phenyl hydrazide showing maximum absorbance at 552 nm and maximum emission at 584 nm. Probe 3 exhibited high sensitivity and extreme selectivity for nitrite ion over other common ions and oxidants (Cl−, ClO−, ClO2 −, ClO3 −, ClO4 −, SO4 2−, SiO3 2−, NO3 2−, CO3 2−) examined in methanol water (1:1, v/v) at pH 7.0. The probe might be a new efficient tool for detection of nitrite ion in natural water and biological system.
