The development of a probe for the selective recognition trivalent cations Al 3+ and In has recently received greater attention due to crucial roles these metal ions play in many biotic material processes.
A novel fluorescent receptor L was synthesized by Schiff base condensation of 1-pyrenemethylamine with the vitamin B6 cofactor pyridoxal. The is highly selective and sensitive towards Zn2+ ions among other tested metal ions. Upon interaction Zn2+, showed a distinct fluorescence enhancement at 485 nm due to excimer formation leading colour change from blue bluish-green. Subsequently, when in situ generated ZnL2 complex interacted various anions amino acids, addition H2PO4- cysteine reinstated...
In this paper, a new Th4+ ion-selective chromogenic sensor (L) was developed by reacting 1,10-phenanthroline-2,9-dicarbohydrazide with 2-hydroxy naphthaldehyde. The sensing ability of L toward investigated in solution and paper strips loaded using spectrophotometric colorimetric methods. selective interaction examined various f-metal ions other selected metal from s-block d-block elements. Results show that the method solution-phase dimethyl sulfoxide/H2O (7:3, v/v) strip methods, naked-eye...
Abstract In this study, a naked‐eye colorimetric probe ( L ) was synthesized by condensation reaction of 9‐fluorenone with 2‐thiophene carboxylic acid hydrazide and characterized various analytical techniques. The presence O, N, S heteroatoms in would modulate the hard soft characters, which is responsible for selective complexation Cu 2+ fluorenone act as signalling unit. sensing ability studied metal ions colorimetric, test paper strip, UV‐visible spectrophotometry DMSO: H 2 O (6 : 4,...

A new fluorescence receptor (E)-2-amino-N′-((3-hydroxy-5-(hydroxymethyl)-2-methylpyridin-4-yl)methylene)benzohydrazide (1) was synthesized by reacting vitamin B6 cofactor pyridoxal with 2-aminobenzohydrazide, and characterized various spectral (FT-IR, 1H NMR, 13C NMR ESI-MS) data. It shows high selectivity sensitivity towards Zn2+ CN− ions among the other tested metal (Cu2+, Co2+, Ni2+, Mn2+, Mg2+, Fe3+, Fe2+, Cd2+, Hg2+, Pb2+, Al3+ Cr3+) anions (F−, Cl−, Br−, I−, NO3−, N3−, HSO4−, H2PO4−,...
Abstract An efficient thiocarbohydrazide based fluorescencesensor S5 for the selective detection of Hg 2+ in semi‐aqueous medium has been successfully designed and synthesized. The absorption (UV‐Vis) emission (fluorescence) properties were studied various solvents. sensor displayed no distinct changes with solvents; however some remarkable noticed fluorescence studies. Solvent dependent spectral characterization was explored via Lippert‐Mataga plot. UV‐Vis studies also revealed that could...
