A water-stable 3D Eu-MOF based on a metallacyclodimeric secondary building unit for sensitive fluorescent detection of acetone molecules

Abstract

Four novel luminescent Ln-MOFs with systematic metallacyclodimeric secondary building units have been designed, synthesized and characterized. It is notable that the compounds can bear acidic or basic conditions in a wide pH range (pH = 3–11). Remarkably, the Eu-MOF (1) can be utilized as a promising luminescent probe for acetone molecules.
