Article Citation - WoS: 4Citation - Scopus: 4A Cyclopalladated Bodipy Construct as a Fluorescent Probe for Carbon Monoxide(Wiley, 2022) Çevik Eren, Merve; Eren, Ahmet; Dartar, Suay; Tütüncü, Büşra Buse; Emrullahoğlu, MustafaBy 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.Article Citation - WoS: 2Citation - Scopus: 2A New Fluorescent 'turn On' Probe for Rapid Detection of Biothiols(Taylor and Francis Ltd., 2020) Üçüncü, Muhammed; Zeybek, Hüseyin; Karakuş, Erman; Üçüncü, Canan; Emrullahoğlu, MustafaWe designed and synthesised a novel molecular probe exhibiting high selectivity and sensitivity towards reactive sulphur species (RSS) over other amino acids and biologically relevant species, as well as scrutinised its spectroscopic behaviours under physiological conditions and in living milieu. We used an electrophilic cyanate group as a masking agent to block the excited state intramolecular proton transfer process of 2-(2-cyanato-3-methoxyphenyl)benzo[d]thiazole (HMBT-OCN), which readily hydrolyses to the highly fluorescent structure, 2-(2'-Hydroxy-3'-methoxyphenyl) benzothiazole (HMBT-OH), in the presence of reactive sulphur species.
