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: 22Citation - Scopus: 22Fluorescein Propiolate: a Propiolate- Decorated Fluorescent Probe With Remarkable Selectivity Towards Cysteine(Royal Society of Chemistry, 2019) Karakuş, Erman; Sayar, Melike; Dartar, Suay; Kaya, Beraat Umur; Emrullahoğlu, MustafaA fluorescent probe decorated with an alkynyl ester unit (e.g. propiolate) displayed a selective turn-on type fluorescent response towards cysteine. Following a sequential addition-cyclisation pathway mediated by the addition of cysteine, the pre-fluorescent dye rapidly transformed into a new structure and induced a fluorescent response clearly observable with the naked eye.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: 5Citation - Scopus: 6Determination of Force-Free Wet Adhesion of Mussel-Inspired Polymers To Spin Labeled Surface(Elsevier, 2017) Kırpat, İklima; Göksel, Yaman; Karakuş, Erman; Emrullahoğlu, Mustafa; Akdoğan, YaşarHydration repulsive forces oppose the adhesive interactions, especially in the force-free conditions. Here, we studied spontaneous wet adhesion of 3,4-dihydroxyphenylalanine (DOPA) functionalized poly(ethylene glycol) (PEG) polymers inspired by marine mussels. Using electron paramagnetic resonance (EPR) spectroscopy, we can monitor spontaneous adhesion of DOPA containing polymer to suspended spin labeled hydrophobic polystyrene nanobeads at molecular level. The surface coverage up to 82% is obtained from EPR measurements. However, in the force-free condition, EPR measurements do not show any detectable DOPA based adhesion to hydrophilic silica nanobead.Article Citation - WoS: 22Citation - Scopus: 23A Guanidinium Modified Rhodamine-Based Fluorescent Probe for in Vitro/Vivo Imaging of Gold Ions(Royal Society of Chemistry, 2015) Karakuş, Erman; Çakan Akdoğan, Gülçin; Emrullahoğlu, MustafaWe devised a rhodamine-based fluorescent probe functionalized with a guanidinium moiety, which both operates efficiently in pure aqueous media and displays a selective fluorescence response to Au3+ ions. We also demonstrated the successful fluorescence imaging of Au3+ within living cells and a vertebrate species, the zebrafish.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: 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.Article Citation - WoS: 44Citation - Scopus: 46A Rhodamine Based "turn-On" Chemodosimeter for Monitoring Gold Ions in Synthetic Samples and Living Cells(Royal Society of Chemistry, 2013) Emrullahoğlu, Mustafa; Karakuş, Erman; Üçüncü, MuhammedA rhodamine-based fluorescent probe, functionalized with an alkyne moiety, shows highly selective recognition towards Au(i) and Au(iii) ions over other metal ions. Probe 1 is successfully employed for the determination of residual gold species in synthetic samples and monitoring the accumulation of gold ions in living cells.Article Citation - WoS: 163Citation - Scopus: 167A Bodipy Aldoxime-Based Chemodosimeter for Highly Selective and Rapid Detection of Hypochlorous Acid(Royal Society of Chemistry, 2013) Emrullahoğlu, Mustafa; Üçüncü, Muhammed; Karakuş, ErmanA BODIPY-based fluorescent probe integrated with an aldoxime unit shows a remarkable fluorescence "turn-on" response to hypochlorous acid (HOCl). The oxidative dehydrogenation of BODIPY aldoxime by HOCl results in a distinct fluorescence enhancement as well as a change in color from red to orange.
