Article Citation - WoS: 51Citation - Scopus: 53Bodipy-Au(i): a Photosensitizer for Singlet Oxygen Generation and Photodynamic Therapy(American Chemical Society, 2017) Üçüncü, Muhammed; Karakuş, Erman; Dartar, Suay; Sayar, Melike; Dartar, Suay; Emrullahoğlu, Mustafa; 04.01. Department of Chemistry; 04.04. Department of Photonics; 04. Faculty of Science; 01. Izmir Institute of TechnologyUpon complexation with Au(I), a photoinactive BODIPY derivative was transformed into a highly photoactive triplet sensitizer. Along with high efficiency in singlet oxygen generation (φδ = 0.84), the new BODIPY-Au(I) skeleton showed excellent photocytotoxic activity against cancer cell lines (EC50 = 2.5 nM).Article Citation - WoS: 80Citation - Scopus: 82Electrophilic Cyanate as a Recognition Motif for Reactive Sulfur Species: Selective Fluorescence Detection of H2s(American Chemical Society, 2016) Karakuş, Erman; Emrullahoğlu, Mustafa; Üçüncü, Muhammed; Emrullahoğlu, Mustafa; 04.04. Department of Photonics; 04. Faculty of Science; 01. Izmir Institute of TechnologyAn ESIPT-based fluorescent dye, 3-hydroxyflavone, is chemically masked with an electrophilic cyanate motif in order to construct a fluorescent probe for cellular sulfur species. This novel probe structure, displays an extremely fast, highly sensitive and selective "turn-on" type fluorescent response toward H2S. We have also documented its utility for imaging of H2S in the living cells.Article Citation - WoS: 22Citation - Scopus: 24A Fluorescein-Based Chemodosimeter for Selective Gold(iii) Ion Monitoring in Aqueous Media and Living Systems(Elsevier Ltd., 2016) Çetintaş, Ceyla; Karakuş, Erman; Emrullahoğlu, Mustafa; Emrullahoğlu, Mustafa; 04.04. Department of Photonics; 04. Faculty of Science; 01. Izmir Institute of TechnologyWe constructed a turn-on type chemodosimeter based upon a fluorescein scaffold for the rapid, selective detection of gold(III) ions over other metal species. This novel probe structure offers distinct features including high water solubility, a low detection limit, rapid response time and applicability in imaging gold(III) ions in living cells.Article Citation - WoS: 36Citation - Scopus: 37A Bodipy-Based Fluorescent Probe for Ratiometric Detection of Gold Ions: Utilization Of: Z -Enynol as the Reactive Unit(Royal Society of Chemistry, 2016) Üçüncü, Muhammed; Karakuş, Erman; Emrullahoğlu, Mustafa; 04.04. Department of Photonics; 04. Faculty of Science; 01. Izmir Institute of TechnologyUsing an irreversible intramolecular cyclisation pathway triggered by gold ions, a boron-dipyrromethene (BODIPY) based fluorescent probe integrated with a reactive Z-enynol motif responds selectively to gold ions. With the addition of gold(iii), the probe displays ratiometric fluorescence behaviour clearly observable to the naked eye under both visible and UV light. © The Royal Society of Chemistry 2016.Article Citation - WoS: 24Citation - Scopus: 24A Ratiometric Fluorescent Probe for Gold and Mercury Ions(John Wiley and Sons Inc., 2015) Üçüncü, Muhammed; Karakuş, Erman; Emrullahoğlu, Mustafa; 04.04. Department of Photonics; 04. Faculty of Science; 01. Izmir Institute of TechnologyA fluorescent probe that displays a ratiometric fluorescence response towards gold and mercury ions has been devised. Emitting at a relatively longer wavelength, the conjugated form of the fluorescent dye transforms in the presence of the gold or mercury ions into a new dye, the molecular structure of which lacks the conjugation and consequently emits at a distinctly shorter wavelength. A fluorescent probe that displays a ratiometric fluorescence response towards gold and mercury ions has been devised. Emitting at a relatively longer wavelength, the conjugated form of the fluorescent dye transforms in the presence of the gold or mercury ions into a new dye (see figure).Article Citation - WoS: 5Citation - Scopus: 5A Rare ?-Pyranopyrazole Skeleton: Design, One-Pot Synthesis and Computational Study(Royal Society of Chemistry, 2016) Üçüncü, Muhammed; Cantürk, Ceren; Emrullahoğlu, Mustafa; Zeybek, Hüseyin; Bozkaya, Uğur; Soydaş, Emine; Şahin, Ertan; Emrullahoğlu, Mustafa; 04.04. Department of Photonics; 04. Faculty of Science; 01. Izmir Institute of TechnologyDrawing upon a consecutive amide coupling and intramolecular cyclisation pathway, a one-pot, straightforward synthetic route has been developed for a range of pyrazole fused γ-pyrone derivatives. The reaction mechanism proposed for the chemoselective formation of γ-pyranopyrazole is furthermore fully supported by experimental and computational studies. © The Royal Society of Chemistry 2016.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, Mustafa; 04.04. Department of Photonics; 04. Faculty of Science; 01. Izmir Institute of TechnologyWe 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.Article Citation - WoS: 118Citation - Scopus: 121A Rhodamine/Bodipy-Based Fluorescent Probe for the Differential Detection of Hg(II) and Au(III)(Royal Society of Chemistry, 2014) Karakuş, Erman; Üçüncü, Muhammed; Emrullahoğlu, Mustafa; 04.04.
