Microwave-assisted synthesis, characterization and modeling of cpo-27-mg metal-organic framework for drug delivery

The coordination polymer CPO-27-Mg was rapidly synthesized under microwave irra-diation. This material exhibits a sufficiently high drug loading towards aspirin (~8% wt.) and paracetamol (~14% wt.). The binding of these two molecules with the inner surface of the metal-organic framework was studied employing the Gaussian and Plane Wave approach of the Density Functional Theory. The structure of CPO-27-Mg persists after the adsorption of aspirin or paracetamol and their desorption energies, being quite high, decrease under solvent conditions. © 2021 by the authors.
