Slow Magnetic Relaxation and Modulated Photoluminescent Emission of Coordination Polymer Based on 3-Amino-4-hydroxybenzoate Zn and Co Metal Ions
As a starting point, a new 3D porous framework with the {[CoL]·0.5DMF·HO} chemical formula (where L = 3-amino-4-hydroxybenzoate) is described. Its performance as a single molecule magnet was explored. The study of magnetic properties reveals that Co-MOF shows no frequency-fdependant alternating curr...

| Sumario: | As a starting point, a new 3D porous framework with the {[CoL]·0.5DMF·HO} chemical formula (where L = 3-amino-4-hydroxybenzoate) is described. Its performance as a single molecule magnet was explored. The study of magnetic properties reveals that Co-MOF shows no frequency-fdependant alternating current (ac) signals under zero direct current (dc) magnetic field, whereas single-molecule magnet behaviour is achieved when Co ions are diluted in a Zn based matrix. Interestingly, this strategy renders a bifunctional [CoZnL] material that is also characterized by a strong photoluminescent emitting capacity. |
