A pyrene-based simple fluorosensor has been synthesized by a one step process. It exhibited high selectivity towards Cu2+ ions via fluorescence enhancement of monomer and excimer emission. The origin formation was examined established to be static in nature from the study absorption excitation spectra. observed emission presence absence ion with varying pH studied provided probable justification. effect portions water content solvent on sensor molecule also examined. found its proper...
A new simple 3-in-1 multi-response thiosemicarbazone-based chemosensor has been synthesized and characterized.
Abstract Rhodamine‐formylaniline conjugate RFA has been developed as a Cu 2+ ‐selective ratiometric fluorescent probe. The probe shows high selectivity towards ion through both its absorption and emission properties; characterized by 1 H NMR, FTIR, ESI‐MS spectroscopy. Sensing of proceed FRET process which is nicely depicted from steady‐state fluorescence lifetime studies. From the measurement lifetime, mechanism established undoubtedly. important parameters regarding FRET, namely energy...
Abstract A simple yet efficient, Hg 2+ selective sensor, based on a fluroescein‐thiophene conjugate, namely, (Z)‐3′,6′‐dihydroxy‐2‐(((3‐methylthiophen‐2‐yl)methylene)amino)spiro[isoindoline‐1,9′‐xanthen]‐3‐one ( FT ) has been designed and synthesized. The compound was well characterized by analytical techniques such as HR‐MS, FTIR, UV‐visible absorption, steady‐state fluorescence time‐resolved spectrophotometric techniques. Comprehensive analysis demonstrated highly specific ultra‐sensitive...
Abstract Two new Manganese (III) Schiff base complexes MnL 2 N 3 ( 1 ) and NCS where HL is 4-bromo-2-[( Z )-{[2-(thiophen-2-yl)ethyl]imino}methyl]phenol) were synthesized characterized by UV–Vis. absorption spectra, FT-IR, photoluminescence (PL) emission TGA Analyses, single-crystal X-ray diffraction technique. Structural studies reveal that the metal sites in all are six-coordinated two phenoxy oxygen imine nitrogen atoms of moles ligand, HL. The geometry around center twisted octahedral...
