Fig. 4.

Morphology of the emerging assemblies. $R_g$ is plotted against $M_w$ for the kinetic run shown in Fig. 3. Circles with a cross correspond to $t\le$10 min and solid circles to 10 $\le \hspace{0.17em}t\hspace{0.17em}\le$ 60 min. Open circles correspond to data for $t\ge 60$ min, which were obtained from 30 angle readings. The black line corresponds to polydisperse rods with $p.d.$ = 1.3 and $M_L$ = 22 $\times {10}^3$ g/(mol⋅nm) (Eq. S4). The blue line corresponds to a best-fit power law. The red bar on the $R_g$ axis corresponds to the $R_g$ value before the aggregation process starts.
