Lastly, we computed the Steinhardt's bond orientational order parameters for each of the reproduced phases (Fig. ). We find that the 1D strings, 2D sheets and 3D aggregates assembled from moderately grafted, weakly grafted, and bare NPs can be clearly distinguished through this order parameter with 1D strings exhibiting high 𝑞 E and high 𝑞 F (as strings have strong 2-fold symmetry), the 2D sheets exhibiting relatively low 𝑞 E and intermediate 𝑞 F , and 3D aggregates exhibiting low 𝑞 E and low 𝑞 F .
