Selective interactions of trivalent cations Fe(3+), Al(3+) and Cr(3+) turn on fluorescence in a naphthalimide based single molecular probe

Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy, 2015

Synthesis and fluorescence turn-on behavior of a naphthalimide based probe is described. Selective interactions of trivalent cations Fe(3+), Al(3+) or Cr(3+) with probe 1 inhibit the PET operating in the probe, and thereby, permit the detection of these trivalent cations present in aqueous samples and live cells. Failure of other trivalent cations (Eu(3+), Gd(3+) and Nb(3+)) to inhibit the PET process in 1 demonstrates the role of chelating ring size vis-à-vis ionic radius in the selective recognition of specific metal ions.
