30 years after C60: Fullerene chemistry with silicon
Frankfurt, Germany (SPX) Mar 19, 2015
The discovery of the soccer ball-shaped C60 molecule in 1985 was a milestone for the development of nanotechnology. In parallel with the fast-blooming field of research into carbon fullerenes, researchers have spent a long time trying in vain to create structurally similar silicon cages. Goethe University chemists have now managed to synthesise a compound featuring an Si20 dodecahedron. The Platonic solid, which was published in the "Angewandte Chemie" journal, is not just aesthetically pleasing, ... read more
