Deskripsi

As a starting point, a new 3D porous framework with the {[CoL]·0.5DMF·H<sub>2</sub>O}<sub>n</sub> 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 (<i>ac</i>) signals under zero direct current (<i>dc</i>) magnetic field, whereas single-molecule magnet behaviour is achieved when Co<sup>II</sup> ions are diluted in a Zn<sup>II</sup> based matrix. Interestingly, this strategy renders a bifunctional [Co<sub>x</sub>Zn<sub>1-x</sub>L]<sub>n</sub> material that is also characterized by a strong photoluminescent emitting capacity.
