Metal-organic frameworks (MOFs) are crystalline, molecular solids built from the linking of organic and inorganic components with coordinative bonds. We design and produce our own families of MOFs based on earth abundant metals to combine sizeable porosities and exceptional chemical stability for applications of environmental relevance. They are labelled as MUV (Materials of the Universidad de Valéncia). Check some of them out:

The use of Metal-Organic Frameworks as crystalline matrices for the synthesis of multiple component or multivariate solids by the combination of diferent linkers or metals into a single material has emerged as a versatile route to tailor the properties of single-component phases or even access new functions. We are also interested in advancing our understanding of how the composition or spatial arrangement of MOF components can determine their function or behavior.

Metal-organic Frameworks are versatile platforms compatible with the use of biological components as amino acids, peptides, nucleobases or enzymes, either as components or functional guests. Compared to other porous materials, the recognition, interaction or structural response of these biomolecules can be precisely tuned with the pore chemistry of MOFs.

Materials scientists are currently shifting from purely inorganic, organic and silicon-based materials towards hybrid organic–inorganic materials to develop increasingly complex and powerful electronic devices. In this context, it is undeniable that conductive Metal–Organic Frameworks and bistable coordination polymers are carving a niche for themselves in the electronics world. The tunability and processability of these materials alongside the combination of electrical conductivity with porosity or spin transition offers unprecedented technological opportunities for their integration into functional devices.

Applications of titanium-organic frameworks in photocatalysis are continuously expanding due to the unique properties that can arise from the combination of high surface area, crystallinity good photostability and photoactivity. Moreover, compared to traditional inorganic semiconductors as TiO2, their photocatalytic activity can be finely tuned by engineering the nature and distribution of the organic and inorganic components in the framework.

The recognition of defect chemistry as a true synthetic tool for targeted creation of defects and controllable performance remains limited by the pool of frameworks explored. The value of defect engineering in controlling the properties of defective frameworks has been beautifully exemplifed and largely demonstrated with UiO-type materials based on Zr(IV) nodes. We aim to extend this chemistry to a broader range of inorganic clusters to exploit the rich chemical and structural versatility ofered by other families of MOFs.
