“…The two-row bright bands are ascribed to the stereoscopic structure of the five-membered and six-membered rings in the cholesteryl groups, and the bands with less contrast in the middle represent the 4Bpy molecules linking the two cholesteryl groups. 24 Due to the stereoscopic structure, the cholesteryl part of C4 seems to be much brighter than the end alkyl chain and the carboxyl end group in STM images [Fig. 1(a) inset image].…”

“…The dependence of the molecular conformation on the electric field originates from the structure-related electron density distribution. The noncentrosymmetry in molecular structures can result in net dipole moments that are one of the main contributors for the responsivity to external electric fields. − The effects of electric fields can also lead to field-induced isomerization and interfacial charge transfer . The strength of the electric field within a STM junction can be as high as 10 8 V/m.…”

Understanding how molecules interact to form large-scale hierarchical structures on surfaces holds promise for building designer nanoscale constructs with defined chemical and physical properties. Here, we describe early advances in this field and highlight upcoming opportunities and challenges. Both direct intermolecular interactions and those that are mediated by coordinated metal centers or substrates are discussed. These interactions can be additive, but they can also interfere with each other, leading to new assemblies in which electrical potentials vary at distances much larger than those of typical chemical interactions. Earlier spectroscopic and surface measurements have provided partial information on such interfacial effects. In the interim, scanning probe microscopies have assumed defining roles in the field of molecular organization on surfaces, delivering deeper understanding of interactions, structures, and local potentials. Self-assembly is a key strategy to form extended structures on surfaces, advancing nanolithography into the chemical dimension and providing simultaneous control at multiple scales. In parallel, the emergence of graphene and the resulting impetus to explore 2D materials have broadened the field, as surface-confined reactions of molecular building blocks provide access to such materials as 2D polymers and graphene nanoribbons. In this Review, we describe recent advances and point out promising directions that will lead to even greater and more robust capabilities to exploit designer surfaces.

“…Sometimes, these dynamics were intentionally provoked by the interaction with the STM-tip. [32][33][34][35][36][37][38][39][40][41][42] Compared to molecular systems adsorbed under UHV conditions, an extra hurdle in probing dynamics in physisorbed self-assembled monolayers at a liquid/solid interface is the fact that molecules are part of a monolayer and often packed in a 2D-lattice. The observation of molecular dynamics at the single molecule level using STM at liquid/solid interfaces imposes a number of challenges.…”

The liquid/solid interface provides an interesting medium for molecular self-assembly and scanning tunneling microscopy is the preferred technique to analyse the structural features of the surface-supported self-assembled monolayers in this medium. An interesting aspect is the phenomenon of molecular dynamics at the liquid/solid interface. In this mini-review, we report on our efforts and strategies to investigate and even induce molecular dynamics at the liquid/solid interface, bringing insight to various kinds of processes such as conformational, translational and adsorption/desorption dynamics.
