The SOAP analysis is conducted on successive snapshots taken along the equilibrium MD trajectories, keeping track of the individual CIT ions -and the SOAP environments they belong to -at every sampled timestep. This analysis allows to reconstruct the dynamic complexity present in the system at various values of E and T . By monitoring the CIT transitions between the different SOAP environments along the simulation trajectories, we can build the normalized transition probability matrices; see Figure ,j. These matrices describe the average probability for a CIT ion belonging to a given SOAP environment to remain there (diagonal entries) or to undergo a transition to another state (off-diagonal entries) in the time interval between two consecutive analyzed snapshots (here, dt = 50 ns). While it is worth underlining again the qualitative value of such data, extracted from transition probabilities in an approximated CG model, one can easily estimate the average transition rates for a CIT ion in the system to exchange between the various clusters as by dividing the off-diagonal probability values by dt. For example, at T = 300 K, the exchange of one CIT from the octahedral cavities (red) to the NP-NP interface occurs with an average rate (frequency) of ∼ 0.002 ns -1 (characteristic transition timescale of ∼ 500 ns). From the diagonal entries, we evince that the blue cluster is the most stable one, while the red one is the most dynamic. The blue domain identifies the interface environment between adjacent TMA-NPs in the FCC lattice. There, the CIT ions interact with both NPs and therefore "glue" them. Nonetheless, this analysis confirms that such "gluing" action is not static, but animated by a certain level of continuous CIT exchange. All these observations are also valid at T = 333 K (Figure ), where the internal CIT dynamics in the superlattice is seen just slightly more pronouncedly than at T = 300 K. In both cases, the transition matrices demonstrate that at E = 0, the CIT ions cannot exchange directly between the octahedral (red) and tetrahedral (cyan) cavities, and that these two environments can communicate only indirectly via the more static interface domain (blue).
