Development of an AIE based fluorescent probe for the detection of nitrate anions in aqueous solution over a wide pH range - RSC Advances (RSC Publishing)

A new type of water-soluble anion fluorescent probe based on ionic interaction-triggered AIE is reported. The positively-charged probe displayed highly selective sensing and imaging of NO3− anions over other environmentally and biologically relevant species through a significant AIE turn-on fluores…
