Simultaneous bioimaging recognition of Al3+ and Cu2+ in living-cell, and further detection of F- and S2- by a simple fluorogenic benzimidazole-based chemosensor.

Abstract

A simple Schiff base (BMSA) prepared from salicylaldehyde and 2-(1H-benzo[d]imidazol-2-yl)aniline was evaluated as an efficient fluorescent chemosensor for the selective recognition of Al3+and Cu2+ over other common metal ions. This sensor could detect Al3+ in CH3OH/PBS with distinct emission red-shift (the detection limit 0.31μM)and Cu2+in CH3OH/Tris-HCL… (More)
