Article Citation - WoS: 2A Reaction-Based Scenario for Fluorescence Probing of Au(iii) Ions in Human Cells and Plants [2](Royal Soc Chemistry, 2023) Eren, Merve Cevik; Eren, Ahmet; Dartar, Suay; Kaya, Beraat Umur; Ucuncu, Muhammed; Varlıklı, Canan; Karakaya, Hüseyin ÇağlarA BODIPY-based fluorophore decorated with a gold specific reactive handle (e.g., 2-alkynylallyl alcohol) displayed a ratiometric fluorescence change in response to Au3+ ions with extraordinary selectivity over other competing metal species, including Hg2+, Cu2+, Zn(2+ )and Pd2+. By way of a gold-catalyzed intramolecular cyclisation-isomerisation reaction sequence, a BODIPY construct with an extended p-conjugation transformed into a new structure with a relatively short p-system. This unique chemical transformation was accompanied by, and resulted in, a dramatic shift in the emission and absorption wavelength, which could be monitored as distinct changes in the color of the solution's emission. Apart from its outstanding analytical performance in solution, including a quick response time (<10 s), unique specificity, a high-fold ratiometric change (62-fold), and a remarkably low detection limit (358 nM), the probe also proved useful in monitoring Au3+ ions in human cells and plants (e.g., Nicotiana benthamiana).Article Citation - WoS: 22Citation - Scopus: 25A Bodipy/Pyridine Conjugate for Reversible Fluorescence Detection of Gold(iii) Ions(Royal Society of Chemistry, 2015) Üçüncü, Muhammed; Karakuş, Erman; Emrullahoğlu, MustafaWe designed a "turn-on" type fluorescent probe based on a BODIPY-pyridine conjugate which exhibits high selectivity towards Au(iii) ions and, also responds to changes in the pH within the acidic pH range. The probe offers features such as a rapid response time, a low detection limit, and high sensitivity and selectivity. The detection of Au(iii) is recognized by a distinct change in the emission intensity which relies on a reversible "ligand to ion" binding mechanism. We also document the utility of the probe for the quantification of gold ion residues in synthetic end products prepared via gold catalysis. © 2015 The Royal Society of Chemistry and the Centre National de la Recherche Scientifique.
