A new multifunctional rhodamine-derived probe for colorimetric sensing of Cu(II) and Al(III) and fluorometric sensing of Fe(III) in aqueous media

- The prepared probe was examined by UV-vis, fluorescence, mass and DFT studies.
- A single probe colorimetrically sense Cu2+ and Al3+ and fluorometrically sense Fe3+.
- Dissociation of probe-Al3+ complex involves the detection of AcO−/F−.
- Provides the sequential detection of Al3+ and AcO−/F−.
