This is one of the most important works that this research group has done in its entire history, and that is saying a lot”, especially in a team that is capable of characterising and synthesising its own carbon nanostructure materials, which has made it one of the most important groups “not only in Europe, but also at international level”. This is what Nazario Martín León, professor in the Department of Organic Chemistry and director of the Organic Molecular Materials group, says when he explains the pioneering work published in the prestigious Nature Synthesis, in which they have managed to control the chirality of a graphene fragment, which opens the door to the possibility of scaling it up and developing materials with new properties.
