A new layer-like metal-organic framework {[Cd4(NDIC)4·5DMF·H2O]DMF}n (NDIC = 5-(5-norbonene-2,3-dicarboximide) isophthalic acid) was synthesized by solvothermal method. It was used as a parent framework to encapsulate Tb3+ cations in Cd-MOF. The obtained composite Tb(3+)@Cd-MOF exhibited excellent luminescence and produced a remarkable quenching effect in the luminescence emission of Tb3+ upon the introduction of Cr3+. Subsequently, Tb(3+)@Cd-MOF was developed as a highly selective and sensitive probe for detection of Cr3+. In particular, the luminescence probe of Cr3+ had a low detection limit (7.5 × 10-8 M), a broad linear range (1 × 10-7-5 × 10-6 M). A paper strip coated with Tb(3+)@Cd-MOF was also shown to be highly selective to Cr3+ under the irradiation of 254 nm UV light of by the naked eyes. This is the first example for detecting metal ions based on a lanthanide functionalized new metal-organic framework (MOF).

A new one dimensional zinc metal organic framework {[Zn(NDIC)·2H2O]·2H2O}n (NDIC = 5-(5-Norbonene-2,3-dicarboximide)Isophthalic acid) has been synthesized under an hydrothermal condition and chosen as a parent framework to sensitize via encapsulating Tb3+ and Eu3+ cations in Zn-MOF. The obtained composite Tb(3+)@Zn-MOF shows excellent luminescence which performs a remarkable quenching effect in the luminescence emission of Tb3+ upon the introduction of Fe3+. Subsequently, Tb(3+)@Zn-MOF as a highly selective and sensitive sensor for Fe3+. Most importantly, the luminescence probe of Fe3+ shows a low detection limit (7.5 × 10?6 M), a broad linear range (2.5 × 10?6–7.5 × 10?5). A paper strip coated with Tb(3+)@Zn-MOF material was also shown to be highly selective for Fe3+ and under the irradiation of UV light of 254 nm by the naked eyes. This is first example for detecting metal ions based on a lanthanide functionalized a new Zn metal–organic framework.
