“…57 Aluminum citrate speciation is very similar to Fe(III), however no large polynuclear species have been structurally characterized. 21,58 Formation of heterometallic or ternary species containing U (VI)O 2 2+ and Fe(III) or Al(III) hydrolysis products are likely to occur in environmental systems, given the ability of the citrate ligand to complex all three metal cations. An Al(III)-U(VI)O 2…”

Organic acids are important metal chelators in environmental systems and tend to form soluble complexes in aqueous solutions, ultimately influencing the transport and bioavailability of contaminants in surface and subsurface waters. This is particularly true for the formation of uranyl citrate complexes, which have been utilized in advanced photo- and bioremediation strategies for soils contaminated with nuclear materials. Given the complexity of environmental systems, the formation of ternary or heterometallic uranyl species in aqueous solutions are also expected, particularly with Al(iii) and Fe(iii) cations. These ternary forms are reported to be more stable in aqueous solutions, potentially enhancing contaminant mobility and uptake by organisms, but the exact coordination geometries of these soluble molecular complexes have not been elucidated. To provide insight into the nature of these species, we have developed a series of geochemical model compounds ([(UO(2))(2)Al(2)(C(6)H(4)O(7))(4)](6-) (U(2)Al(2)), [(UO(2))(2)Fe(2)(C(6)H(4)O(7))(4)](6-) (U(2)Fe(2)-1) and [(UO(2))(2)Fe(2)(C(6)H(4)O(7))(4)(H(2)O)(2)](6-) (U(2)Fe(2)-2) and [(UO(2))(2)Fe(4)(OH)(4)(C(6)H(4)O(7))(4)](8-) (U(2)Fe(4))) that were characterized by single-crystal X-ray diffraction and vibrational spectroscopy. Mass spectroscopy was then employed to compare the model compounds to species present in aqueous solutions to provide an enhanced understanding of the ternary uranyl citrate complexes that could be relevant in natural systems.

“…Also, an excessive amount of Al 3+ ions can damage the central nervous system (CNS), and the population becomes at high risk for various neurodegenerative diseases [7,8] . It may also lead to various diseases, such as Alzheimer's disease and Parkinson's disease [7,9–12] . Acid rain leaches aluminium from the soil, which increases the concentration of Al 3+ ions in the surface water and is harmful to aquatic life.…”

Developing fluorosensors for the efficient detection of aluminium (Al 3 + ) ions and electron-deficient nitroaromatic compounds (NACs) is in high demand but challenging. This report introduces a benzoxazole-based off-on-off fluorosensor for the cascade detection of Al 3 + ions and electron-deficient NACs. Upon addition of Al 3 + ions, the probe BPMP displays a bright blue fluorescence under the exposure of 365 nm UV light radiation in an H 2 O/DMSO (1 : 1 v/v) medium due to the chelation of Al 3 + ions disrupting the ESIPT process involved in probe BPMP. The detection limit for Al 3 + ions is found to be 13 nM, which is significantly lower than many chemosensors available in the literature. The 1 : 1 stoichiometry of the chelated complex between BPMP and Al 3 + ions is confirmed by Job's plot and also by 1 H NMR titration investigation. More impor-tantly, the Al 3 + ions chelated BPMP complex is further used as a fluorescent turn-off probe for the detection of electrondeficient NACs with the detection as low as 10 À 7 M. Based on these chemically encoded inputs and the corresponding optical output, we have constructed one input and one output based YES, and NOT logic gate with BPMP and BPMP-Al 3 + complex as input respectively and also dual inputs and single optical output-based INHIBIT logic gates. Also, BPMP-doped paper strips-based test kit analysis has been demonstrated as a displayable photonic device for on-spot detection. The performance of BPMP and Al 3 + ions chelated BPMP complex toward Al 3 + ions and electron-deficient NACs demonstrated that BPMP could be served as a sensitive probe and could be employed for real sample analysis.
