In systems that self-assemble in solution, the formed assemblies reach a dynamic supramolecular equilibrium, characterized by continuous exchange of molecular units among assemblies and with the environment (Figure ). To explore the factors that control such complex dynamics, we here employ a minimalistic model of a supramolecular polymer system, constituted by monomeric units that mutually interact in a directional, short-ranged and reversible way, spontaneously polymerising into one-dimensional fibres during MD simulations (Figure ).
