3D water-stable europium metal organic frameworks as a multi-responsive luminescent sensor for high-efficiency detection of Cr 2 O 7 2− , MnO 4 − , Cr 3+ ions and SDBS in aqueous solution

A 3D water-stable europium metal organic framework has been synthesized. Fluorescence measurements show that the MOF can selectively and sensitively detect Cr 2 O 7 2− , MnO 4 − , Cr 3+ ions and SDBS in aqueous solutions.
