Hierarchical two-dimensional molecular assembly through dynamic combination of conformational states at the liquid/solid interface

Abstract

Self-sorting multiple building blocks for correctly positioning molecules through orthogonal recognition is a promising strategy for construction of a hierarchical self-assembled molecular network (SAMN) on a surface. Herein we report...

Chirality in porous self-assembled monolayer networks at liquid/solid interfaces: induction, reversion, recognition and transfer

“…Our most recent results on the formation of a highly hierarchical SAMN, yet not related to chirality, support that this must be the case. 96 Even though stereocontrolled epitaxial growth of SAMNs orthogonal to the surface is a challenging topic, only few scattered investigations have been performed, in spite of its potential relevance to SURMOFs. 62 This is probably not only because it may seem unsurmountable to control the intermolecular interactions in multiple dimensions to build up a stereochemically defined architecture.…”

Self-sorting assembly of artificial building blocks

“…95 The resultant covalent-supramolecular polymer was stiff and showed high damping capacity due to its network structure. Apart from the examples presented above, other orthogonal supramolecular interaction pairs were also well explored, including hydrophobic interaction/high affinity between fluorinated moieties, 96 hydrogen bond/hydrophobic interactions, 97 hydrogen bond/coordination bonds, 61,98 and hydrogen bond/ p-p interaction. 99 Meanwhile, some other strong interactions or driving forces could also be combined and utilized for constructing self-sorting systems, including crystallization of small molecules and macromolecules, 16 liquid crystalline ordering-driven assembly, 17,100-104 etc.…”

Halogen bond-directed self-assembly in bicomponent blends at the solid/liquid interface: effect of the alkyl chain substitution position

“…As reported previously, alkyl chains are a key factor in stabilising self-assembled structures, particularly on a highly-oriented pyrolytic graphite (HOPG) substrate, and they also play a decisive role in the molecular arrangement of two-dimensional structures. 10,11 In this context, Xu and Deng et al studied the self-assembly of anthraquinone derivatives, 11 and they found that upon variation in the substitution positions of the alkyl chains, the anthraquinone core adopted different arrangements at the 1-octanoic acid/HOPG interface. These structures were organised by hydrogen bonding, and were revealed by STM.…”
