چکیده انگلیسی
A novel florescence sensor (Q-BODIPY) based on quinoline-Bodipy (quinoline-boradiazaindacene) was prepared by 'click chemistry' in several stages. The sensing actions of Q-BODIPY were confirmed by UV-vis titration, emission and excitation spectroscopic studies in presence of Mn2+, Co2+, Ni2+, Cu2+, Zn2+, Cd2+, Sn2+, Hg2+, Pb2+, La3+, Ga3+, Er3+ and Yb3+ ions in methanol:H2O (1:1) medium. Whereas some metal ions can only cause quenching effect on the fluorescence intensity of Q-BODIPY, some of them show an increase in fluorescence intensity. The stoichiometry of host-guest complexes formed was determined by Jobâ²s plot method. The binding constants were calculated by Stern-Volmer method. As a fluorescence sensor, Q-BODIPY shows the best selectivity performance against Zn2+ ions in according to all spectroscopic data.
