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; Karakaya, Hüseyin Çağlar; Eren, Ahmet; Varlıklı, Canan; Dartar, Suay; Dartar, Suay; Kaya, Beraat Umur; Kaya, Beraat Umur; Ucuncu, Muhammed; Varlıklı, Canan; Karakaya, Hüseyin Çağlar; 04.01.

Faculty of ScienceA 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 - Scopus: 3A Reaction-Based Scenario for Fluorescence Probing of Au(iii) Ions in Human Cells and Plants(Royal Soc Chemistry, 2023) Eren, Merve Cevik; Emrullahoğlu, Mustafa; Dartar, Suay; Varlıklı, Canan; Kaya, Beraat Umur; Varlikli, Canan; Emrullahoglu, Mustafa; 04.01.

Department of Chemistry; 04.04. Department of Photonics; 01. Izmir Institute of Technology; 04. Faculty of ScienceBy introducing a palladium ion into the backbone of BODIPY, we devised a cyclopalladated BODIPY construct that was almost non-emissive in the absence of any analyte but became highly fluorescent upon interacting with carbon monoxide (CO) in solution and in living cells. A process of ortho-carbonylation and depalladation mediated by the specific binding of CO to palladium, promoted the release of the heavy atom from the fluorophore and consequently generated a fluorescence signal with an exceptionally high (60-fold) enhancement ratio.
