The importance of aluminum usage in our everyday life and its adverse impact on health and the environment stimulate the development of excellent probes for the detection of Al 3+ ions. In this study, we developed a luminescence enhancement-based detection probe for the selective detection of Al 3+ ions. For this purpose, we developed water-dispersible 2-furoic acid-capped LaF 3 :5%Tb 3+ nanocrystals (NCs) via the microwave irradiation method. Here, 2-furoic acid acts as a surfactant and an antenna for the Tb 3+ ions. Oxygen in the furan ring has a hard base nature and prefers to bind with hard acid-natured metal ions. Upon excitation at 258 nm, the NCs show characteristic Tb 3+ emissions via 2furoic acid sensitization. The excitation and emission spectra of the NCs increased continuously with the gradual addition of Al 3+ ions from 1 to 700 μm in the aqueous medium. More than 2-fold enhancement was found for 700 μM Al 3+ ions. The luminescence enhancement results from aggregation caused by hard acid and hard base interactions between Al 3+ ions and oxygen atoms in the furan ring. In this way, the quenching of nonradiative energy transfer by solvent molecules was reduced, and the efficiency of energy transfer from ligand to Tb 3+ ions was increased. The luminescence increment is highly selective toward Al 3+ ions with very minimal interference. The developed method shows a remarkably high sensitivity for Al 3+ ion detection, and the calculated LOD was 1.67 μM, which is much lower than the maximum aluminum content allowable by the WHO in drinking water. Furthermore, we applied this method for the determination of Al 3+ ions in actual water samples.

“…The Na + ion located in the analogous crown ether structure is formed by one TEBA Al 3+ ions is urgent. To date, several chemical sensors based on organic compounds [34][35][36][37][38] and MOFs [39][40][41] for Al 3+ ion detection have been reported. However, sensors based on discrete lanthanide metal-organic assemblies are rarely reported.…”

Luminescent probes have wide applications in biological system analysis and environmental science. Here, one novel luminescent dinuclear europium compound with a crown ether analogous ligand was synthesized through a solvent–thermal reaction. Through transformation, upon the addition of Al3+ ions to the N,N′-dimethyl formamide solution of the europium compound, the luminescent intensity of the characteristic emission of Eu3+ decreased, and a new emission peak appeared at 346 nm and increased rapidly. The luminescent investigation indicated that it could act as a highly sensitive and selective luminescent probe for Al3+ ions. Moreover, mass spectrometry and single-crystal X-ray diffraction confirmed the formation of a new more stable trinuclear aluminium compound during the sensing process.
