The molecular legacy of Antoni Gaudí

A paper on novel carbon cage structures, based on models designed by the Spanish architect Antoni Gaudí, has featured in the international ChemistryWorld News.

The paper, published in late 2015 by Prof. Dage Sundholm, Dr Lukas Wirz and Distinguished Professor Peter Schwerdtfeger proposed a new family of cavernous all-carbon structures. These molecular cage structures are constructed by edge subdivisions and leapfrog transformations from cubic polyhedra or their duals. 

The obtained structures were then optimized at the density functional level. The hollow carbon structures represent a new class of carbon allotropes, which could lead to many interesting applications.

The so-called ‘gaudiene molecule’ is a class of polyhedral molecules, an all-carbon molecule consisting of 72 carbon atoms forming a hollow structure of Oh symmetry.

The name reflects the inspiration for the initial polyhedron concept, which was inspired by the work of the Spanish architect Antoni Gaudí.

Gaudiene can be constructed from a truncated octahedron with two thirds of the edges replaced by –C≣C– units. Quantum chemical calculations showed that β-C72 is an aromatic molecule with a rather large optical gap. It is there that the novel class of hollow carbon structures is proposed 

Gaudienes are more general than carbomers as the insertion of dicarbon units may not take place in every chemical bond.

The work was a truly international effort between collaborators and support in New Zealand, Finland, Denmark, Sweden and Germany.
