The Monte Carlo simulations were performed using HPMC, 33 a plugin to the HOOMD-Blue simulation toolkit,. HPMC simulations work by performing moves of either a translation or rotation of the particles. If the move leads to no overlap between any hard particles, it is accepted, whereas if an overlap between neighbouring particles occurs then the move is rejected. Therefore the simulations are often deemed to be temperature independent as each move either leads to no change in energy, or an infinite increase. However, in our case we applied interactions between neighbouring particles which caused the simulation results to be affected by temperature. The simulations were slowly cooled over the transition point, where k B = 0.00831kJmol -1 K -1 .
