A novel strategy for the synthesis of samarium/europium-metal organic frameworks, and their utilization for detection of Cr3+, Pb2+, and acetone as a luminescent sensor with superior selectivity and sensitivity properties

With outstanding detection selectivity and sensitivity characteristics, samarium/europium-metal organic frameworks (Sm/Eu-MOF) is capable of functioning as a versatile light-emitting sensor particularly for detecting acetone, Cr3+, 3 + , and Pb2+ 2 + in aqueous environment. While considering maximum detectable concentrations of 0.85 mu M, 0.46 mu M, and 1.04 mu M, respectively, competitive energy interactions for acetone, absorption of energy for Cr3+, 3 + , and substitution of ions for Pb2+ 2 + are the elucidated mechanisms of detecting these substances by Sm/EuMOF. Successful formulation and synthesis of a core-shell structured Sm/Eu-MOF, which has endurance to acid/ alkali conditions and hydration/heat-stability, can be accomplished by utilizing Samarium and Europium nitrate ions, terephthalic acid, and 2, 5-furandicarboxylic acid. The recovery rate of acetone, Cr3+, 3 + , and Pb2+ 2 + detection from real samples were 95.0-101.0 %, 99.8-101.0 %, and 99.9-104.0 %, respectively.
