New ‘chemical architecture’ developed in Spain highlighted in a prestigious American chemistry journal

One of the most prestigious international chemistry journals, the Journal of the American Chemical Society*, highlights on the cover of its latest issue a paper by Professor Pablo Ballester and his team at the Catalan Institute of Chemical Research (ICIQ).

The investigation focuses on the design of a new method for obtaining interpenetrated multimolecular architectures (supermolecules formed by several smaller molecules).

The application of this new methodology has allowed for the first time to construct a molecule that results from the assembly of four components in which one cyclic component is linearly threaded by another component, like a needle and a thread.

This peculiar and complex ‘supermolecule’ maintains its structure thanks to intermolecular interactions that exist between the different components that formed the structure. These components act as the ‘glue’ of the new chemical architecture.

This kind of ‘interpenetrated molecules’ can respond to external stimuli and modify its properties accordingly. Furthermore, they constitute the basic structural units for the construction of molecular machines and other systems capable functioning like a motor, rotors and even the muscles at microscopical level.

Pablo Ballester, the leader of the group that has developed this new molecule, has been awarded this year with the Organic Chemistry National Award by the Spanish Royal Society of Chemistry.

Pablo Ballester and his group continue studying the design of more complex molecules capable of acting as capsules, containers and molecular reactors with different applications in medicine, new technologies and molecular engineering.

The deposition of this sort of ‘supermolecules’ on appropriate solid surfaces will lead to applications in nanorobots.
