Figure 3: Internal cavity and the pores found in nanocapsule crystals.

(a) The crystal structure of nanocapsule based on L-1; red=O, yellow=S and blue=N. Disorder has been removed for clarity. The encapsulated void volume of 1,719 Å3 is shown as 50% transparent green isosurface. (b) Space filling representations of the nanocapsule derived from L-1 showing two types of pores A and B.
