Triazine Derivative for Fluorescence Sensing of Zr⁴⁺, Fe³⁺ Ions and Acetone

Abstract

2,2',2''- (1,3,4,tribenzoic acid (L, H 3 TATIB) fluorescence response chemosensor has been synthesized by one pot reaction and its fluorescent behaviors to transition metal ions were systematically investigated. The experimental results show that the recognition of Zr 4＋ and Fe 3＋ is realized in N,N-dimethylformamide (DMF) aqueous solution; The compound L can effectively detect acetone in organic solvent. The detection limits of Zr 4＋ and Fe 3＋ are 3.60×10 -6 and 1.33×10 -6 mol/L, respectively. It was preliminarily explored that compound L was used as a fluorescent probe to identify Fe 3＋ ion in human urine and water samples.

Zirconium-Directed Supramolecular Self-Assembly of Coenzyme A@GNCs with Enhanced Phosphorescence for Developing Ultrasensitive Tracer Probe of Dipicolinic Acid, a Biomarker of Bacterial Spores

“…In previous studies, detection of Zr 4+ has been mainly achieved through inductive coupled plasma/glow discharge mass spectrometry (ICP-MS, GC–MS) , and reversed phase liquid chromatography (RP-LC). , In spite of their high sensitivity, these methods require sophisticated instrumentation with high cost and utility of toxic organic solvents, limiting their practical applications. Few spectrophotometric , and fluorescent approaches were also employed for Zr 4+ detection. Despite of their fast analysis and easy operations, those methods exhibited poor sensitivity and needed incorporation of high-cost DNA recognition probes …”

A Multi-response Aluminum Metal-organic Frameworks for Fluorescence Sensing of Fe3+, Sr2+, SiO3 2− and Toluene

“…In this work, a new complex, Al-MOF[L=2,2',2'-([1, 3, 5]-triazine-2,4,6-triimino)tribenzoic acid] has been prepared by reaction of L with Al(III) salt in DMF solution. The ligand L is synthesied by 'one pot' reaction in glacial acetic acid solution according to the previous work [34]. The Al-MOF was investigated for multiple fluorescence response to Fe 3+ , Sr 2+ , SiO 3 2− ions and toluene, especially it is first reported that the fluorescence intensity of Al-MOF is enhanced when Fe 3+ , Sr 2+ and SiO 3 2− ions are added in DMF/H 2 O solution, respectively.…”

A Highly Stable Multi-response Zirconium(IV) Metal-Organic Frameworks for Fluorescence Sensing of Fe3+, Cr2O72- and Organic Small Molecules

“…The ligand L is synthesized by "one pot"' reaction in glacial acetic acid solution, and the complexation ratio of ligand L to Zr 4 ＋ was also determined according to the previous work. [64] The Zr-MOF was investigated for the fluorescence response to the metal cations, anions and organic small molecules, especially it is reported that Zr-MOF can detect CCl 4 and xylene in DMF solution.…”
