A novel turn-off fluorescent Pb(II) probe based on 2,5-di(thien-2-yl)pyrrole with a pendant crown ether

[Display omitted] The synthesis, optical, and ion-sensing characteristics of a novel compound, 1, which is based on a 2,5-di(thien-2-yl)pyrrole scaffold with a 15-crown-5 unit, are reported. It is noteworthy that 1 can be utilized for turn-off fluorimetric detection of Pb(II) ions. The fluorescence...

More Information
Summary:[Display omitted] The synthesis, optical, and ion-sensing characteristics of a novel compound, 1, which is based on a 2,5-di(thien-2-yl)pyrrole scaffold with a 15-crown-5 unit, are reported. It is noteworthy that 1 can be utilized for turn-off fluorimetric detection of Pb(II) ions. The fluorescence response is based on cation-mediated reductive photoinduced electron transfer.
