| 摘 要： | The ruthenium unit was introduced into the redox-active molecular polygon to assembly new Ru-Fc metallocycles (Compound 1), in which the redox active (ferrocene) and fluoresecent (ruthenium) signaling subunits are directly attached by the putative cation-binding sites. The compound 1 displayed high selectivity for Ca^2 by electrochemical tests. The measurements of the fluorescence spectra on titration of 1 with Ca^2 , Li^ , Na^ , K^ , Mg^2 or Ba^2 ion indicate the unique ability of 1 to detect Ca^2 ions selectively.

| Abstract: | The ruthenium unit was introduced into the redox-active molecular polygon to assembly new Ru-Fc metallocycles (Compound 1), in which the redox active (ferrocene) and fluoresecent (ruthenium) signaling subunits are directly attached by the putative cation-binding sites. The compound 1 displayed high selectivity for Ca2+ by electrochemical tests. The measurements of the fluorescence spectra on titration of 1 with Ca2+, Li+, Na+, K+, Mg2+ or Ba2+ ion indicate the unique ability of 1 to detect Ca2+ ions selectively. |
