Particle in a box : A gold nanoparticle is encapsulated in a fifth‐generation guest dendrimer, which binds to a host self‐assembled monolayer surface (see figure). The nanoparticle encapsulated in the “molecular box” is a supramolecular junction that exhibits single‐electron tunneling at room temperature. STM shows that the junction exhibits Coulomb staircase behavior along with negative differential resistance under ambient conditions, but not in ultrahigh vacuum.
