ResumoA rhodamine-based fluorescent probe with an aldehyde functionality as a binding site was developed for the selective detection of bisulfite anion in aqueous ethanol media. The new fluorescent probe showed an excellent selectivity for bisulfite anion over other anions. The bisulfite-induced ring opening of spirolactam of the rhodamine moiety resulted in the dual chromo- and fluorogenic observation.
