Abstract:
Tailoring the architecture of porous two-dimensional networks formed by molecules is essential for developing functional materials with low dimensionality. Here we present bicomponent porous networks with tunable pore-sizes that were formed by self-assembly of hydrogen-bonding molecules at the liquid/graphite interface. Scanning tunneling microscopy investigations demonstrate the formation and coexistence of three polymorphs. It is found that the occurrence of these polymorphs depends critically on the surface coverage. Further on, atomic force microscopy measurements, spectroscopic studies, and dynamic light scattering investigations show the propensity of one of the two molecular components to form aggregates beyond the monolayer. We discuss how these preorganized aggregates in solution may affect the self-assembly at the interface.

Intermolecular Forces in Solutions
When the strengths of the intermolecular forces of attraction between solute and solvent species in a solution are no different than those present in the separated components, the solution is formed with no accompanying energy change. Such a solution is called an ideal solution. A mixture of ideal gases (or gases such as helium and argon,...
