This review aims at giving the readers the basic concepts needed to understand two-dimensional bimolecular organizations at the vacuum–solid interface. The first part describes and analyzes molecules–molecules and molecules–substrates interactions. The current limitations and needs in the understanding of these forces are also detailed. Then, a critical analysis of the past and recent advances in the field is presented by discussing most of the key papers describing bicomponents self-assembly on solid surface in an ultrahigh vacuum environment. These sections are organized by considering decreasing molecule–molecule interaction strengths (i.e. starting from strong directional multiple H bonds up to weaker nondirectional bonds taking into account the increasing fundamental role played by the surface). Finally, we conclude with some research directions (predicting self-assembly, multi-components systems, and nonmetallic surfaces) and potential applications (porous networks and organic surfaces).

“…In the field of molecular motors, focus has been given to studies at room-temperature and some important contributions have been published with dynamic molecular systems in these conditions [61][62][63][64][65]. A recent work [63] reports a walking molecule moving freely at room-temperature between two stationary points. The authors analyzed the movements of a divalent bis(imidazolyl) molecule, that they called a "walker", which moves with an inchworm mechanism by attachment and detachment cycles between two immobilized cobalt porphyrins.…”

The development of organic devices has been focused in their miniaturization in order to obtain denser and faster electronic circuits. The challenge is to build the devices adding atom by atom or molecule by molecule until the desired structure is achieved. To do this job, techniques able to see and manipulate matter at this scale are needed. Scanning tunneling microscopy has been the selected technique by scientists to develop smart and functional unimolecular devices. This review article compiles the latest developments in this field giving examples of supramolecular systems monitored and fabricated at molecular scale by bottom-up approaches using STM at solid/liquid interface.
