The first simulations we performed were when only window-to-window (and by analogy arene-to-arene) packing is preferred. The low temperature RDFs only evidenced one ordered phase (Figs. and), a representative cluster of which is shown in Fig. (b) (see Fig. for the analogous arene-to-arene configuration). To determine how the phase behaviour changes with temperature and also patch width, σ ang , we compared the similarities of RDFs at each temperature and σ ang to the RDF of the ordered phase (Fig. ), and coloured our phase diagram (Fig. ) such that the darker orange the region of the phase diagram, the more similar our simulated structure is to the ordered phase, as described in Section S4.
