A single probe for solvent dependent optical recognition of iron(II/III) and arsenite: discrimination between iron redox states with single crystal X-ray structure evidence

The detection and discrimination of Fe(2+) and Fe(3+) ions have been investigated using a simple probe (L), produced by the condensation of ethylenediamine and 3-ethoxysalicyaldehyde. Single crystal X-ray structures demonstrate that L interacts with Fe(2+) and Fe(3+). In aqueous-DMSO media, the L re...

Sumario:The detection and discrimination of Fe(2+) and Fe(3+) ions have been investigated using a simple probe (L), produced by the condensation of ethylenediamine and 3-ethoxysalicyaldehyde. Single crystal X-ray structures demonstrate that L interacts with Fe(2+) and Fe(3+). In aqueous-DMSO media, the L recognises AsO(2)(−) by fluorescence and colorimetry techniques. The AsO(2)(−) aided PET inhibition and H-bond assisted chelation enhanced fluorescence (CHEF) boost fluorescence by 91-fold. The L can detect 0.354 ppb Fe(2+), 0.22 ppb Fe(3+) and 0.235 ppt AsO(2)(−).
