Two novel Se/O mixed-donor molecular probes based on ferrocene and anthracene units
摘要:
Two mixed-donor molecules containing ferrocene and anthracene moiety, 1 and 2, have been designed and synthesized as potential multichannel probes for transition metal cations. They displayed switch-on fluorescence intensity only with Cu2+ among the metal ions examined. Electrochemistry and UV-vis spectra studies showed that Cu2+ induces the oxidation of ferrocene unit and then forms stable Cu+ complex. (C) 2014 Elsevier B.V. All rights reserved.
