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 () signals under zero direct current () 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.
