    A novel dual channel responsive zinc(II) probe
    (Pergamon-Elsevier Science Ltd, 2014) Karakaya, Serkan; Algı, Fatih
    A novel compound, 1, which is based on a 1,10-phenanthroline scaffold with cofacial BODIPY units, is synthesized via a three-step reaction sequence. It is noteworthy that 1 can be utilized for both visual and turn-off fluorometric detection of Zn2+ ions in aqueous acetonitrile solution. The fluorescence response is based on cation-mediated oxidative photoinduced electron transfer (PET). The digital action of a two-input NOR logic gate is also demonstrated. (C) 2014 Elsevier Ltd.

    Synthesis of cyclen bodipy dyad and its metal complexes: evaluation of anion recognition features
    (Muğla Sıtkı Koçman Üniversitesi Fen Bilimleri Enstitüsü, 2019) Algı, Fatih; Karakaya, Serkan
    In this study, a new compound, viz. 4,4-Difluoro-8-(1,4,7,10-tetraazacyclododecane)methyl-1,3,5,7-tetramethyl-2,6-diethyl-4-bora-3a,4a-diaza-s-indacene (1), and its metal complexes (1-Zn,1-Cu,and1-Ni) are synthesized and spectroscopicallycharacterized (UV-Vis, luminescence-fluorescence, NMR,FTIR, and MS). Anion sensing properties of compound 1 and itsmetal complexes (1-Zn, 1-Ni and 1-Cu) are tested in the presence of various anionic species in acetonitrile media.Fluorescence measurements indicated that, 1-Ni and 1-Cu do not have any selectivity towards various anions except weakinteractions. On the other hand 1-Zn shows good response and selectivity toward acetate ion based on fluorescenceenhancement. In addition, JOB studies demonstrate that the interaction between 1-Zn and acetate ion were with a ratio of1:2 and limit of detection (LOD) of 1-Zn was calculated as 4.76x10-6 M for acetate ion detection. Moreover, 1-Znprovides acertain change in color in the presence of acetate. The results demonstrate that 1-Zn can be utilized for fluorogenic andnaked eye detection of acetate anion.
