“…There are more and more Al 3+ selective fluorescent sensors being reported in recent years [9][10][11][12][13][14][15][16][17]. However, most of them are mainly based on the change of single emission intensity such as PET which is easy to be affected by instrumental efficiency and environmental condition [18][19][20][21][22]. The design of ratiometric probes which can eliminate these deficiencies through simultaneous recording ratio signals of two emissions at different wavelengths is still challenge.…”

In this study, a novel chemosensor (HL) for Al 3+ which contain rhodamine and naphthalene moieties has been designed and synthesized. In the presence of Al 3+ , the receptor exhibited a strong, increasing fluorescent emission centered at 550 nm at the expense of the fluorescent emission of HL centered at 520 nm. We proposed that the addition of Al 3+ triggered intramolecular fluorescence resonance energy transfer (FRET) from naphthalene to Rhodamine 6G.

“…For a complex with 1:1 (H:G) stoichiometry ratio, the association constant with non-linear relationship could be determined by titration curves (Fig. 3) of Benesi-Hilderbrand method [9] according to the eqn 1 [10,11] for UV-visible titration and eqn 2 [12,13] for fluorescent titrations data.…”

A dual sensor based on benzoxazole containing moiety S3 was successfully synthesized and applied for detection of CN− ion. The S3 molecule changed its colour for dark brown to dark green on addition of the CN− ion only in DMSO solvent. The limit of detection (LOD) and association constant (Kass) values was 0.4 × 10−6 M and 1.0 × 107 M−1; and 0.46 × 10−4 M and 1.0 × 105 M−1 determined by UV-visible spectroscopic titration and fluorescence titration, respectively.

“…On the incremental increase in the amount of Al 3+ , these two signals have been decreased gradually. Moreover, a new absorption band was displayed at 414 nm with an increase in absorption [41] . Furthermore, two clear isosbestic regions at 335 and 364 nm were displayed that were clearly demonstrated for the formation of a new complex that is in equilibrium with the receptor.…”

Among various known hydroxyquinolines, 8-hydroxyquinoline (8-HQ) is the most prevalent moiety due to excellent property for the formation of the complex with different metal ions and anions, and utilized in a wide variety of applications in pharmacological and medicinal fields. 8-Hydroxyquinoline moiety and its analogues acts as fluorophoric ligands on complex formation with alkali and alkaline as well as transition metal ions and anions, thus, considered as an ideal building block in metallo-supramolecular chemistry for recognition, separation, and quantitative investigation of cations. 8-Hydroxyquinoline moiety is also used in various applications for the advancement of novel fluorescent chemosensors in a wide variety of areas viz., material chemistry, bioorganic chemistry, molecular imaging, analytical chemistry, molecular recognition, medical and biological science communities. The present review emphasises on the progress of sensing properties of 8-HQ centred small-molecule fluorescent chemosensors towards several metal ions viz.
