Lanthanide(Tb3+, Eu3+)-functionalized a new one dimensional Zn-MOF composite as luminescent probe for highly selectively sensing Fe3+
摘要:
A new one dimensional zinc metal organic framework {[Zn(NDIC)center dot 2H(2)O]center dot 2H(2)O}(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 Tb(3+)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 Fe - shows a low detection limit (7.5 x 10(-6) M), a broad linear range (2.5 x 10(-6) -7.5 x 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. (C) 2018 Elsevier Ltd. All rights reserved.

developed as a highlyselective 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 highlyselective to Cr3+ under the irradiation of 254 nm UV light of by the naked eyes. This is the first example for detecting metal ions
