The phase diagram shows that the ordered structure is present in a large area of phase space, approximately σ ang = 0.1 -0.6. At higher values of σ ang , an amorphous phase forms instead, an example of which is shown in Fig. . When σ ang = 1.0, although there is another phase that has an ordered RDF at low temperature (Fig. )), on further inspection the orientation of the cages were disordered (Fig. ). As such we deduced that this phase behaves more like a plastic crystal -where the structure has positional order but orientational disorder-a phase behaviour, unsurprisingly, unreported for porous organic cages, and as such was not considered an ordered phase. Therefore, these results indicate that cages that only interact through the same type of facets (window-to-window or arene-to-arene) produce a single ordered phase in the solid state.
