“Fluorine leaves nobody indifferent; it inflames emotions be that affections or aversions. As a substituent, it is rarely boring, always good for a surprise, but often completely unpredictable"

Manfred Schlosser. Angew. Chem. Int. Ed. 1998, 110, 1496.

Group

Our research group is made up of investigators from the Department of Chemistry at the Universitat Autònoma de Barcelona. The group is led by Dr. Adelina Vallribera and Prof. Roser Pleixats, professors of the Unity of Organic Chemistry at the Department of Chemistry at the UAB.

The FluNanoChem project, led by A. Vallribera and R. Pleixats, has been framed in two major areas of chemistry such as organofluorine chemistry and nanomaterials, and aims to generate knowledge to address some of the challenges proposed in HORIZON 2020 (Nanotechnology and Advanced Materials, Health).

In the field of organofluorine chemistry, our goal is to prepare and study new hydrophobic dyes derived from classical colorants. The motivation is the staining of surfaces (cotton, glass, paper ..) in order to obtain improved properties such as anti-microbial, self-cleaning, fluorescense and anti-corrosion properties. The introduction of reactive groups for covalent attachment of the dye to the surfaces will prevent discoloration. Another milestone is the design and preparation of fluorinated analogues of drugs to increase their lipophilicity, bioavailability and metabolic stability.

In the field of nanotechnology and new materials, we are working on the synthesis, characterization and application in catalysis of metal nanoparticles, and mesoporous silica nanoparticles (MSN) functionalized with chiral organocatalysts. Advances in catalysis, either with transition metals or simple organic molecules (organocatalysis), have an impact on the development of efficient, affordable and sustainable industrial processes. Due to its high surface area, derived from the nanometer-size, the nanoparticles have a large number of catalytic sites on its surface, increasing the catalytic efficiency. We propose the preparation of various soluble metal nanoparticles in a sustainable medium such as water, allowing the use of aqueous media in various catalytic processes, and an easy recycling of the nanocatalyst. We have also initiated a research focused on the preparation and characterization of periodic mesoporous organosilica nanoparticles (PMON) for biomedical applications.
