A single molecular probe for multi-analyte (Cr³⁺, Al³⁺and Fe³⁺) detection in aqueous medium and its biological application

Abstract

An ESIPT based fluorescent sensor 1 was developed, which could selectively detect and differentiate trivalent metal ions Cr(3+), Al(3+) and Fe(3+) in aqueous medium. The cell imaging experiments confirmed that 1 can be used for monitoring intracellular Cr(3+) and Al(3+) levels in living cells.
