Abstract An imidazole-Schiff base fluorescent probe EBI was designed and synthesized for the sensitive selective detection of Al3+. The exhibits good anti-interference performance against Al3+ in presence multiple metal ions. reaction reached platform about 30 min after adding Al3+, fluorescence limit 1.62 nM. coordination ratio to is 1:1, between carbonyl group, hydroxyl –HN–N=C– limits molecular distortion quenching effect photoelectron transfer, thus inducing enhancement green fluorescence. can be recovered used alternately by EDTA In addition, EBI–Al3+ PO43− also evident selected anion range. applied successful monitoring living cells.
