Abstract

Endohedral fullerenes encapsulating a helium atom, i.e., He@C₆₀ and He@C₇₀, at occupation levels of 30% were prepared by rational chemical synthesis. The existence of weak interactions between the inner helium and the outer fullerene cages was demonstrated by experimental and computational investigations.
