“…Upon incremental addition of Zr(IV) (5 × 10 −4 M), the absorption intensities increase at 250 nm and 360 nm, whereas the absorption band at 300 nm shows gradual decrease as depicted in Figure 1b. In order to calculate the association constant (K a ), the Benesi‐Hildebrand (B‐H) graph was plotted using the data obtained from titration studies, and Equation () given below was used 40 :

1 / ((), normalA goodbreak- A_{o}) goodbreak= 1 / ({}, K_{a} ((), A_{\max} goodbreak- A_{o}) normalC) goodbreak+ 1 / ((), A_{\max} goodbreak- A_{o})

where A o , A and A max define the absorbance intensity of 2a in the absence, presence and maximum concentration of Zr(IV)ions, respectively. C denotes the concentration of Zr(IV) ions used in titration experiment.…”

Zirconium, a transition metal with medical importance, is widely used and has a generally safe profile. However, prolonged and continuous exposure can lead to detrimental consequences; this necessitates the development of quick and efficient sensors for the detection of Zr(IV) ion. The current investigation focuses on the synthesis and characterization of 4‐(methylthio)benzaldehyde derived Schiff base functionalized organosilatranes (2a–2b). The probe 2a has been utilized as a UV–visible absorption based, highly selective and sensitive sensor for the detection of Zr(IV) ion with a limit of detection and association constant values of 10.89 × 10−7 M and 3.1 × 104 M−1, respectively. The practical applicability of the synthesized sensor has been determined in water samples, yielding good percentage recovery rates. The cytotoxicity assay has been performed using SAF‐1 cell line, rendering the synthesized compounds non‐toxic. Furthermore, molecular docking has been performed against cyclooxygenase‐2 in order to determine anti‐inflammatory activity of synthesized ligand with a binding energy score of −7.51 kcal mol−1.

“…43 Importantly, organosilanes coupled with 1,2,3-triazole have the potential to be employed as chemosensors since they are nontoxic. 44 Taking into account the foregoing discussion, molecular stitching of different structural motifs such as 2-morpholinoethanamine, 1,2,3-triazole and organosilanes was carried out. The synthesized compound 5a displayed a dual sensing response towards Zn 2+ and Hg 2+ recorded by both UV-visible and fluorescence spectroscopy.…”
