L'invention porte sur des compositions à bicouches qui sont utiles en tant que couches de transport d'électrons. Les bicouches ont une première couche contenant un matériau de transport d'électrons et une seconde couche contenant un fullerène. L'invention porte également sur des diodes électroluminescentes organiques comprenant les bicouches de transport d'électrons. |
