Thus, our data support a general trend: increasing the monomer-monomer interactions produces longer fibres, but reduces the molecular exchange at the equilibrium (Figures , and S2-S12). Such behavior fits qualitatively well with recent observations on, e.g., BTA systems, where increasing the number of carbon atoms in the monomer side-chains (favoring their self-assembly in aqueous environment) produces more persistent and less dynamical fibres in water.
