Weakly bonded salt is a key ingredient for high-purity Li@C60 film

As well as making it one of the most widely recognized molecules, the distinctive soccer ball shape of C60 gives it some useful properties. One of which is thought to be electrical conductivity when multiple molecules are close together. Efforts have therefore been made to optimize C60 so that it can be applied to electronic devices. Now, researchers at the University of Tsukuba have devised a way of depositing films based on C60 to provide a robust model to study. Their findings are published in The Journal of Physical Chemistry Letters.
