چکیده
A simple 2-hydroxy-1-naphthaldehyde (receptor 1) serves as a selective chemosensor for Al(3+) based on chelation-enhanced fluorescence (CHEF). The receptor 1 exhibited a high association constant with micromolar detection for Al(3+) in EtOH-H(2)O solution.

A turn-on and reversible Schiff base fluorescence sensor for Al3+ ion.
A simple Schiff-base receptor 2 was prepared. It exhibits an “off-on-type” mode with high sensitivity in the presence of Al3+. The receptor 2 exhibited a high association constant with submicromolar detection for Al3+ in EtOH–H2O (95:5 v/v) solution. The addition of EDTA quenches the fluorescence of the receptor 2·Al3+ complex offering receptor 2 as a reversible chemosensor.
متن کاملAn amine/imine functionalized microporous MOF as a new fluorescent probe exhibiting selective sensing of Fe3+ and Al3+ over mixed metal ions
Nowadays metal-organic frameworks with multiple luminescent centers are very fascinating as multifunctional luminescent material because of their luminescence properties, which could be systematically tuned by deliberate use of organic ligands and metal ions. In this research, we explored a microporous mixed-ligand MOF for highly selective and sensitive detection of metal ions. A two-fold inter...
متن کاملPreparation and Application of Al3+ - Sensor Based On (2Z) — Methyl 2 — ((z) (p-tolylimino) -3-Ethyl —4-0xothiazolidin —5— Ylidene Acetate in PVC Matrix
Al3+-Potentiometric sensor, based on (2Z) -methyl 2- ((z) (p-tolylimino)-3-ethyl -4-oxothiazolidin -5- ylidene) Acetate (MTEOY) as a neutral ionophore, was successfully developed for the detectionof Al3+ in aqueous solutions. The electrode responds to Al3+ ion with a sensitivity of 19.8 ± 0.1 mV/decade over the range 1.0 x 10-8- 1.0 x 10-1 mol LT' and in a pH range of 3.0-9.0. The electrodeshow...
متن کاملA novel diethyl 2-(9-fluorenyl) malonate functionlized SBA-15 for selective optical sensing of Iron
In this study, highly ordered mesoporous silica material (SBA-15) functionalized with Diethyl 2 - (9 -fluorenyl) malonate as a flourophore is reported. The anchoring of flourophores to the hydroxyl group on SBA-15 surface was done with post synthesis method. The obtained materials were characterized by small and wide angle X-ray diffraction, N2 adsorption–desorption, Fourier transform infrared ...
متن کاملA differentially selective sensor with fluorescence turn-on response to Zn2+ and dual-mode ratiometric response to Al3+ in aqueous media.
A novel quinoline-coumarin (QC) fluoroionophore conjugated by means of a triazolyl-pyrrolidinyl linker exhibits differential dual selectivity for Zn(2+) and Al(3+) in mixed media. QC acts as a turn on fluorescence sensor for Zn(2+) while exhibiting overall ratiometric selectivity for Al(3+) in aqueous media. Moreover, QC exhibited preferential second mode of selectivity for Al(3+) as it ratiome...
