“…It is well known that self-assembly of functional systems could lead to different types of nanostructures [5][6][7][8] via non-covalent interactions. Intermolecular interaction plays an important role in molecular recognition processes, which has been demonstrated from steric hindrance 9,10 to intermolecular hydrogen bonding, [11][12][13][14] metal coordination, [15][16][17][18] and van der Waals interactions. [19][20][21][22] Among them, hydrogen bonds are of particular importance in the association of molecules due to their high directionality and selectivity.…”

“…Direct and real space information of bonding and coordination of organic molecules with the substrate was obtained. [14][15][16][17][18][19][20] In the present study, the adsorption of rhodamine B (RB) has been studied by cyclic voltammetry and in situ STM. RB is a typical dye of rhodamine group.…”

In situ scanning tunneling microscopy (STM) has been first employed to investigate the adsorption of RB (rhodamine B) on solid surface in solution. An I/Au(111) (iodine-modified Au( 111)) surface was used as a substrate for molecular adsorption. In situ STM imaging revealed a highly ordered RB molecular adlayer. A unit cell with parameters of a ) 1.71 nm and b ) 2.25 nm was determined. Higher resolution STM images disclosed the structural details of the molecular adlayer. On the basis of STM results, the RB molecule is proposed to adsorb on the I/Au(111) surface by its two diethylamino functional groups in an edge-on orientation. The orientation was related to the molecular degradation.

“…The mechanisms of molecular self-organization have been the subject of numerous investigations aimed at the realization of building blocks designed so as to spontaneously form 2D monolayers with specific topologies. Intermolecular interaction may be driven by various molecular recognition processes, from steric hindrance , to hydrogen bonding, − metal coordination, − or interdigitation of alkyl chains, − The latter may be strongly favored by adsorption on the surface of highly oriented pyrolytic graphite (HOPG). As a matter of fact, the value of the alkyl-chain period allows an adsorption in registry with HOPG along its ⟨1,0,0⟩ axis according to the Groszek model. − It has been noticed that the distance which minimizes the energy of side interaction between alkyl chains, 4.26 Å, exactly matches a period of ⟨1,0,0⟩ rows .…”

We have analyzed by STM the detailed structures of a series of nanoporous honeycomb networks stabilized by alkyl chain interdigitation on graphite at the liquid−solid interface, that is, clip-like noncovalent bonding. The variations observed as a function of the length of the peripheral aliphatic chains show that the assembly is directed not only by lateral intermolecular interactions but also by the adsorption site on the substrate. We derive an atomically accurate model for the registry with graphite of our nanoporous model series of systems. In full agreement with the quantitative model, the pore areas vary step-by-step by more than one order of magnitude along the whole series while preserving the detailed features of the graphite-induced alkyl chain interdigitation. The largest pores observed correspond to a ratio of uncovered substrate area as large as 35%.
