Multifunctional Lanthanide-Based Metal-Organic Frameworks Derived from 3-Amino-4-hydroxybenzoate: Single-Molecule Magnet Behavior, Luminescent Properties for Thermometry, and CO2Adsorptive Capacity
Herein, we describe and study a new family of isostructural multifunctional metal-organic frameworks (MOFs) with the formula {[LnL(OH)(DMF)]·5HO}(where (HL) is 3-amino-4-hydroxybenzoic acid ligand) for magnetism and photoluminescence. Interestingly, three of the materials (Dy-, Er-, and Yb-based MOF...

| Sumario: | Herein, we describe and study a new family of isostructural multifunctional metal-organic frameworks (MOFs) with the formula {[LnL(OH)(DMF)]·5HO}(where (HL) is 3-amino-4-hydroxybenzoic acid ligand) for magnetism and photoluminescence. Interestingly, three of the materials (Dy-, Er-, and Yb-based MOFs) present single-molecule magnet (SMM) behavior derived from the magnetic anisotropy of the lanthanide ions as a consequence of the adequate electronic distribution of the coordination environment. Additionally, photoluminescence properties of the ligand in combination with Eu and Tb counterparts were studied, including the heterometallic Eu-Tb mixed MOF that shows potential as ratiometric luminescent thermometers. Finally, the porous nature of the framework allowed showing the COsorption capacity. |
