Supramolecular chemistry is the “chemistry beyond the molecule” and deals with the interactions between chemical species in an ordered and hierarchical way, leading to the formation of well-defined supramolecules. We mainly work in the fields of molecular recognition, programmed folding and self-assembling processes, using a large variety of experimental and theoretical approaches. The discovery, preparation and study of new synthetic receptors for biologically interesting molecules and ions (especially anions) are our main activities. We also use supramolecular approaches to synthetic procedures, such as templated synthesis, dynamic combinatorial chemistry and constitutional dynamic chemistry. Additionally, we collaborate with several groups (both at IQAC and outside) to study biomolecular and biomimetic systems from a supramolecular point of view.
