Highly selective and sensitive colorimetric probe for Al3+ and Fe3+ metal ions based on 2-aminoquinolin-3-yl phenyl hydrazone Schiff base

Schiff Bases and Multidentate Organic Compounds as Fluorescent Sensors of Al3+: Photophysical, Fluorescent Bioimaging and the Mechanisms

“…The colorimetric probe based on 2-aminoquinolin-3-yl phenyl hydrazone Schiff base L19 ((E)-3-((2phenylhydrazono)methyl)quinolin-2-amine) for the detection of Al 3 + was recently reported. [65] The absorption and fluorescence spectra in ethanol of the compound, demonstrated the high selectivity and sensitivity towards the metal ions like Al 3 + and Fe 3 + over the other metal cations. L19 displayed high selectivity and sensitivity towards Al 3 + with a detection limit of 1.06 × 10 À 6 M and 1 : 1 stoichiometry.…”

“…Additionally, the use of test strips coated with L18 demonstrate the applicability of the probe to detect Al 3+ in real samples. The colorimetric probe based on 2‐aminoquinolin‐3‐yl phenyl hydrazone Schiff base L19 (( E )‐3‐((2‐phenylhydrazono)methyl)quinolin‐2‐amine) for the detection of Al 3+ was recently reported [65] . The absorption and fluorescence spectra in ethanol of the compound, demonstrated the high selectivity and sensitivity towards the metal ions like Al 3+ and Fe 3+ over the other metal cations.…”

Catechol-Containing Schiff Bases on Thiacalixarene: Synthesis, Copper (II) Recognition, and Formation of Organic-Inorganic Copper-Based Materials

“…Synthetic macrocyclic compounds, such as calixarenes, thiacalixarenes, resorcinarenes, pillararenes, and others, have excellent complexing properties and are often selective for a certain substrate [ 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 ]. The introduction of fragments of Schiff bases into the structure of (thia)calixarenes makes it possible to increase both the efficiency and selectivity with respect to metal cations.…”

Highly sensitive naphthalimide based Schiff base for the fluorimetric detection of Fe3+

“… 45–53 Patil et al have developed a colorimetric probe based on 2-aminoquinolin-3-yl phenyl hydrazone Schiff base for Fe 3+ chemosensor. 54 Recently, a new Schiff-based macrocyclic host has been reported for the sensing and removal of Fe 3+ . 55 Finelli et al reported salen-type anthracene-based probe for the selective fluoro-colourimetric detection of Fe 3+ .…”
