Zinc(ii)-based coordination polymer encapsulated Tb³⁺ as a multi-responsive luminescent sensor for Ru³⁺, Fe³⁺, CrO₄ ^2-, Cr₂O₇ ^2- and MnO₄.

ABSTRACT: A zinc(ii)-based coordination polymer (CP), namely [Zn(modbc)₂] _n (Zn-CP) (modbc = 2-methyl-6-oxygen-1,6-dihydro-3,4'-bipyridine-5-carbonitrile), has been synthesized and characterized. Single-crystal structural determination reveals that Zn-CP is a two-dimensional framework structure with tetranuclear homometallic Zn₄(modbc)₄ units cross-linked by modbc. The excellent luminescence as well as good stability of Zn-CP do not enable it to have selective sensing capability for different ions. After encapsulation of Tb³⁺ in Zn-CP, the as-obtained fluorescent functionalized Tb³⁺@Zn-CP maintained excellent luminescence as well as stability, which made it a highly selective and sensitive multiresponsive luminescent sensor for
