Macrocyclic and Supramolecular Chemistry of Organoboron and Organotin Compounds

The combination of metal ions with di- or oligofunctional ligands via self-assembly allows for the
generation of a large number of metallosupramolecular architectures having either macrocyclic, cage-like
or polymeric structures. A series of different applications are envisioned for these systems, and one of the
main targets today is the generation of discrete or infinite systems having cavities, channels or pores for
diverse objectives such as selective molecular and ion recognition, separation, storage, transport and
catalysis.
Cocrystal formation and crystal engineering

Crystal engineering deals with the structural analysis and characterization of crystalline solid
phases, and aims at the generation of solids having particular properties. Since variations in the
structural organization of a chemical compound in the solid state influence the physical and
chemical properties on the macroscopic level, it is expected that crystal engineering will have
important implications in diverse fields such as materials and pharmaceutical sciences.
In this regard we are exploring covalent macromolecular assemblies based on organoboron compounds, and
macrocyclic and microporous systems based on diorganotin(IV) carboxylates and dithiocarbamates. In both
cases we have been able to prepare a number of architectures with interesting 0D, 1D, 2D and 3D structures,
including MOFs, COFs and HOFs.
