    • We could also envisage that the transition is affected by a change of conformation of the alkyl chains. (20) However, FTIR spectroscopy shows that the proportion of gauche conformations is not affected by the tube to filament transition, whatever the chain length of the bisurea (see Figure S4 in the Supporting Information)

    • To test this assumption, the stability of the monomer to filament transition was studied by isothermal titration calorimetry (ITC) (see Figure S5 in the Supporting Information). No influence of the alkyl chain length on the filament stability could be detected. Unfortunately, this test is not conclusive, because the uncertainty of the ITC experiment, although small, is larger than the effect detected by DSC
