“…The results are very similar to previously mentioned values, where in this case, the additional stabilization of the SAMN with an increase in the length of the alkyl chain for one methylene unit amounts to 1.27 kJ mol –1 . Interestingly, all of these results are in extremely good agreement with the previously studied systems in the Matsuda group (additional 2.8 kJ mol –1 stabilization as the alkyl chain increases for two methylene units), which was evaluated at an octanoic acid/HOPG interface. , This strongly suggests that the quantitative evaluation of the Gibbs free energy change relating to structural modification of the studied molecule is independent of the model used to fit the 2D concentration-dependence data, which makes the data analysis quite robust.…”

Molecular self-assembly, a promising strategy for modifying surfaces on the nanometer scale, is essential for developing functional materials in electronics, catalysis, or twodimensional (2D) crystal engineering. In this work, we are shifting attention to the physical chemistry of the process at a molecular level through a study of the effect of concentration on the overall process of self-assembled molecular network formation using scanning tunneling microscopy. The overarching idea is to correlate experimental results with analytical thermodynamic models to improve the understanding of supramolecular chemistry in two dimensions by obtaining quantitative data. For this purpose, a series of isophthalic acids have been chosen as a model system. The effect of the concentration on the adsorption behavior, focusing on the surface coverage, has been evaluated at the nanoscale. Our results confirm the existence of a critical concentration above which self-assembly occurs and that a change in the molecular structure (the length of the alkyl chain) has a remarkable impact on the value of this critical threshold. Finally, we report highly cooperative behavior in studied systems, which presents one of the rare examples of quantitative measurement of cooperative phenomena at the liquid/solid interface.

“…Additionally, the alkyl chains in both DA compounds (other 1 and other 2) are interdigitated with each other between the adjacent layers. [48][49][50] Note that such unique structures are only obtained when non-fluorinated TCNQ is utilized as an acceptor unit.…”

“…Fine-tuning of supramolecular structures on surfaces is essential for the fabrication of functional nanomaterials and molecular machines. 1 By introducing noncovalent interactions such as dispersion forces, 2 metal coordination, 3 hydrogen bonding, 4 and halogen bonding, 5 various types of fascinating supramolecular structures have been constructed. Scanning tunnelling microscopy (STM) has been used for the direct visualization of two-dimensional (2D) molecular arrangements on surfaces.…”
