Fig. 5. Snapshots of MD simulations on pre-assembled PMI nanoscale ribbons. (A) Radial distribution function of the PMI center to center distance for both 1 and 1′. (B) Schematic of the two vectors (nin-plane, nnormal) used to describe the rotational order of PMI assemblies. (C) Top view of 1′ after equilibrium is reached. (D) Top view of 1 after equilibrium is reached. (E) Side view of 1′. (F) Side view of 1. Explicit water molecules used in the simulations are omitted from snapshots for clarity.
