“…However, compared to other transition metal ions, the detection of Al 3+ has always been problematic due to the lack of spectroscopic characteristics and poor coordination ability [11]. In addition, most of the reported Al 3+ sensors suffer from interference caused by Fe 3+ and Cu 2+ [12][13][14], poor water solubility [15] and tedious synthetic methods of preparation [16].…”

“…1 In organisms, aluminium which is present as Al 3+ , is highly important in order to maintain the health. However, an excess of Al 3+ has severe toxicity, which not only influences plant growth 2 but also damages the central nervous system to cause human illnesses like dementia and impairment of memory, idiopathic Parkinson's disease, Alzheimer's disease and even breast cancer.…”

First, 7-hydroxy-4-methylcoumarin (5.00 g, 0.0284 mol) and hexamine (10.0 g, 0.071 mol) in acetic acid (37 mL) were stirred for 5.5 h at 95 C. Then, hydrochloric acid (75 mL, HCl: H2O = 84:100, v/v) was added and further College of Chemistry and Chemical Engineering, Southeast University, Nanjing, Jiangsu 211189, P. R. ChinaA novel chemosensor L based on coumarin Schiff-base was synthesized and investigated. Sensor L showed remarkable selectivity for Al 3+ in Tris-HCl aqueous buffer solution (pH 7.2), and the selectivity was not affected by the presence of a large excess of other competitive ions. The sensor responded rapidly to Al 3+ in aqueous solutions with a 2:1 stoichiometry. Meanwhile, it indicated significant improvement of quantum efficiency and ideal fluorescent lifetime.

“…26,27 Even so, the detection of Al(III) has always been problematic because of its pH-dependence in aqueous solution and its poor coordination ability comparing to transition metals. 28,29 Well established procedures for quantitative detection of aluminium have been reviewed by Tria et al, 30 and referenced by Lide. 31 Moreover, recently some novel sensors have been developed.…”

Porphyrazines possessing non-coordinating alkyl (propyl) and aralkyl (4-tert-butylphenyl) groups in the periphery were studied as optical sensors for a set of mono-, di-and trivalent cations. Investigated porphyrazines in the UV-Vis monitored titrations revealed significant responses towards aluminium and gallium cations, unlike other metal ions studied. Additionally, porphyrazine possessing 4-tert-butylphenyl peripheral substituents showed sensor property towards ruthenium cation and was chosen for further investigation. The presence of isosbestic points in absorption spectra for its titration with aluminium, gallium and ruthenium cations, accompanied by a linear Benesi-Hildebrand plot, proved complex formation. The continuous variation method was used to determine binding stoichiometry in 1:1 porphyrazine-metal ratio. X-Ray studies and density functional theory calculations were employed to investigate octa(4-tert-butylphenyl)-porphyrazine structure. The results helped to explain the observed selectivity towards certain ions. Interaction between ion and porphyrazine meso nitrogen in a Lewis acid-Lewis base manner is proposed.
