H2O@C60 is a remarkable molecule that consists of a polar molecule encapsulated into a highly symmetric and nonpolar cage. For H2O@C60, the polarity is no longer associated with its external shape. The encapsulated water molecule can rotate freely around the center inside the cage. In this ...
Polar organic molecules with longer methylene chains and nonpolar molecules such as dinitrogen and methane were completely excluded. The guest-inclusion properties could be explained by the ion-dipole interaction between the host and the guest, which is proportional to the dipole moment of the guest ...
