The BTA monomers are intrinsically different from the M units. In fact, while the flat symmetry and directional interaction between the BTA cores produce an ordered monomer stacking as in the M model, the higher-resolution description of the BTA monomers accounts (to some extent) for the effect of molecular flexibility (whereas the M units are rigid). Investigating how similar is the supramolecular equilibrium of the BTA model to that of the M model could provide insights on how molecular flexibility impacts the dynamics of the assembled system. Also, it could reveal to what extent the complexity of a realistic system is lost when considering a minimalistic representation such as that of M model.
