    • note
    • The XPS spectrum of the sample prior to annealing exhibits two individually resolved nitrogen peaks at 399.8 and 397.9 eV binding energy, thus corresponding to the imine and amine groups, whereas only the peak at 399.8 eV remains after annealing at 300°C; this observation is attributed to the "symmetrization" of all the imine nitrogen atoms, which is consistent with the transformation of 1 into 1b.

    • Based on a time-lapse series (see the Supporting Information), an approximate value for the diffusion barrier and for the condensation energy can be deduced. According to the procedure described in reference [16], a value of 0.6 eV for the diffusion energy and 0.3 eV for the condensation energy are derived. Mainly, these values should only reflect the energy range for diffusion and condensation as they are obtained in a semi-quantitative way.

    • note
    • This conclusion is deduced through comparison of the surface area which is covered by the network before and after the second evaporation.
