摘要：

Owing to their immense biological significance, development of sensors for the selective detection of alkaline earth metal ions has attracted vast research interest. In this article we have reported the synthesis, characterisation and ion binding studies of a new Ru-II-polypyridyl-crown-anthraquinone complex (5). Studies confirm selective binding of Ba-II, Sr-II and Ca-II ions, with KBa2+ > KSr2+ >> KCa2+, over all other metal ions, to the crown ether moiety and not to the methoxy anthraquinone component, the latter being the second binding site available and known for its affinity towards alkaline earth metal ions from one of our previous reports.
