Article Citation - WoS: 23Citation - Scopus: 23Bodipy-Vinyl Dibromides as Triplet Sensitisers for Photodynamic Therapy and Triplet-Triplet Annihilation Upconversion(Royal Society of Chemistry, 2021) Dartar, Suay; Üçüncü, Muhammed; Karakuş, Erman; Hou, Yuqi; Zhao, Jianzhang; Emrullahoğlu, MustafaWe devised a new generation of halogen-based triplet sensitisers comprising geminal dibromides at the vinyl backbone of a BODIPY fluorophore. Incorporating geminal dibromides into the pi-conjugation of BODIPY enhanced intersystem crossing due to the heavy atom effect, which in turn improved the extent of excited triplet states.Article Citation - WoS: 56Citation - Scopus: 55A Bodipy-Based Fluorescent Probe To Visually Detect Phosgene: Toward the Development of a Handheld Phosgene Detector(John Wiley and Sons Inc., 2018) Sayar, Melike; Karakuş, Erman; Güner, Tuğrul; Yıldız, Büşra; Yıldız, Ümit Hakan; Emrullahoğlu, MustafaA boron-dipyrromethene (BODIPY)-based fluorescent probe with a phosgene-specific reactive motif shows remarkable selectivity toward phosgene, in the presence of which the nonfluorescent dye rapidly transforms into a new structure and induces a fluorescent response clearly observable to the naked eye under ultraviolet light. Given that dynamic, a prototypical handheld phosgene detector with a promising sensing capability that expedites the detection of gaseous phosgene without sophisticated instrumentation was developed. The proposed method using the handheld detector involves a rapid response period suitable for issuing early warnings during emergency situations.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; Kurulgan Demirci, Eylem; Sayar, Melike; Dartar, Suay; Emrullahoğlu, MustafaUpon 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: 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, MustafaUsing 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, MustafaA 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: 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.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, MustafaWe described the design and synthesis of a molecular sensor based on a rhodamine/BODIPY platform that displayed differential fluorescence responses towards Hg2+ and Au3+ and demonstrated its utility in intracellular ion imaging.
