A multifunctional metal–organic complex fluorescent probe for highly sensitive detection of lysine, CrO42-/Cr2O72-, Fe3+ and nitro-aromatic compounds
Water contamination caused by organic and inorganic compounds represents an urgent global issue. It is meaningful to detect these compounds. A metal–organic complex (Zn-HTBA) was investigated as a multifunctional fluorescent probe which showed exceptional fluorescence characteristics. The Zn- HTBA can specifically detect lysine in water through fluorescence enhancement, and the detection limit was 0.17 μM. The Zn-HTBA also selectively detect CrO42-/Cr2O72- and Fe3+ with the detection limits of 0.014/0.022 and 0.12 μM through fluorescence quenching. In addition, the Zn-HTBA was found to sensitively detect nitroaromatic compounds in ethanol through fluorescence quenching. The possible detection mechanisms were studied in detail through UV–Vis, PXRD, XPS, etc. The mechanism of Zn-HTBA to detect CrO42-/Cr2O72-, Fe3+ and 2-nitrotoluene was energy competition, and the mechanism of Zn-HTBA to detect lysine was the formation of hydrogen bonds.
期刊介绍：
Inorganica Chimica Acta is an established international forum for all aspects of advanced Inorganic Chemistry. Original papers of high scientific level and interest are published in the form of Articles and Reviews.
Topics covered include:
• chemistry of the main group elements and the d- and f-block metals, including the synthesis, characterization and reactivity of coordination, organometallic, biomimetic, supramolecular coordination compounds, including associated computational studies;
• synthesis, physico-chemical properties, applications of molecule-based nano-scaled clusters and nanomaterials designed using the principles of coordination chemistry, as well as coordination polymers (CPs), metal-organic frameworks (MOFs), metal-organic polyhedra (MPOs);
• reaction mechanisms and physico-chemical investigations computational studies of metalloenzymes and their models;
• applications of inorganic compounds, metallodrugs and molecule-based materials.
Papers composed primarily of structural reports will typically not be considered for publication.
