A multifunctional Eu-CP as a recyclable luminescent probe for the highly sensitive detection of Fe3+/Fe2+, Cr2O72, and nitroaromatic explosives

A multifunctional Eu-CP as a recyclable luminescent probe for the highly sensitive detection of... A novel 2D lanthanide coordination polymer {Eu-CP (1)} based on a 3-bis(3-carboxyphenyl)imidazolium (L) ligand was successfully assembled through a solvothermal method. Luminescence tests indicate that 1 has excellent selectivity and sensitivity to detect Fe3+/Fe2+, Cr2O72, and a series of nitroaromatic explosives. Interestingly, 1 can effectively distinguish CrVI anions (CrO42/Cr2O72), which is difficult for most of the reported CPs. Furthermore, in the detection process, 1 can be simply and quickly regenerated and reused at least five times. As far as we know, 1 is the first multifunctional Eu-CP used as a luminescent probe to detect Fe3+/Fe2+, Cr2O72, and a series of nitroaromatic explosives (NAEs) based on the imidazolium derivative. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Dalton Transactions Royal Society of Chemistry

Abstract

A novel 2D lanthanide coordination polymer {Eu-CP (1)} based on a 3-bis(3-carboxyphenyl)imidazolium (L) ligand was successfully assembled through a solvothermal method. Luminescence tests indicate that 1 has excellent selectivity and sensitivity to detect Fe3+/Fe2+, Cr2O72, and a series of nitroaromatic explosives. Interestingly, 1 can effectively distinguish CrVI anions (CrO42/Cr2O72), which is difficult for most of the reported CPs. Furthermore, in the detection process, 1 can be simply and quickly regenerated and reused at least five times. As far as we know, 1 is the first multifunctional Eu-CP used as a luminescent probe to detect Fe3+/Fe2+, Cr2O72, and a series of nitroaromatic explosives (NAEs) based on the imidazolium derivative.
