Abstract

A novel flavin-dipicolylamine conjugate was designed for highly selective and sequential recognition of zinc and phosphate ions based on OFF-ON-OFF mode of detection. While lower detection limits were obtained toward zinc ion recognition in the two solvents studied here, different stoichiometric requirement and hence different mode of coordination was also observed and evaluated. Furthermore, the DPF-zinc complex was found to be highly selective for phosphate anion over other anions studied. Variation in the detection limit for phosphate over pyrophosphate was observed making it a model capable of differentiating between AMP from ADP or ATP.
