Abstract

A new type of fluorescent probe (L) for Fe³⁺ based on C [double bond, length as m-dash] N isomerization was synthesized. It shows fluorescence enhancement (turn-on) response for Fe³⁺ in aqueous media (v(CH₃CN) : v(H₂O) = 1 : 9). The complexation mode and the corresponding fluorescent enhancement mechanism were elucidated by IR spectra, transient spectra, Job plot, and DFT calculations.
