Hierarchical Supramolecular Self‐Assembly of Nanotubes and Layered Sheets

Abstract

Roll up! Roll up! The self‐assembly of para‐terphenylen‐1,4′′‐ylenebis(dodecanamide) in THF results in either multiwalled, rolled‐up, open‐ended organic nanotubes or layered sheets (see picture) depending on the conditions used. The nanotubes can co‐assemble with fullerene to produce quasi‐cable‐like structures with C60 nanowires inside the nanotubes.

Hollow Micro/Nanomaterials with Multilevel Interior Structures

“…[146] By hierarchical supramolecular selfassembly of a small organic non-amphiphilic molecule, paraterphenylen-1,4 00 -ylenebis(dodecanamide), Bo and co-workers prepared rolled-up multiwalled nanotubes. [147] Other multiwalled tubular materials including polymer tubes by wetting of the AAO template [148] and by a self-rolling method, [149] Cu 7 S 4 by a sacrificial templates method, [150] and some others.

An infinite chainmail of M6L6 metallacycles featuring multiple Borromean links

“…Close inspection of the small solid needles reveals that some have a series of very small holes along the needle axis, The formation of hollow, tubular crystals of organic material remains relatively rare but can occur through a number of proposed mechanisms. These include preferential dissolution of the centre of a rod-like crystal, 43 spontaneous dissolution-recrystallisation processes of single crystals 44 or of assemblies of precursor nanoparticles, 45 dissolution-recrystallisation processes induced by sonochemistry 49 or by solution-mediated dehydration or solvent-exchange of solvate crystals, 46 rolling up of layered crystals, 47 or through crystal growth under diffusion limited conditions with a high crystallisation rate. 48 The observations of complex 1 detailed above, notably the small holes in the small solid needles and formation of large tubular crystals from the solid needles on an increase in temperature (and thus solubility), are consistent with the tubular morphology being due to a spontaneous localised dissolution-recrystallisation process that occurs around the initial crystals.…”

Twisted Helical Microfibers by Hierarchical Self‐Assembly of an Aromatic Oligoamide Foldamer

“…Subsequently, several layer sheets were overlapped together and may further roll up via both intermolecular hydrogen bonding and van der Waals forces of aliphatic chains, resulting in formation of primary microfibers (Figure 4c). [21][22][23] When the incubation time was increased, the larger-scaled micro objects were observed, which might be generated through the direct fusion of the primary microfibers, since some partially fused besom-like structures were found in the intermediates ( Figure S13). And almost all the primary fibers were ultimately converted to micro objects after a week.…”
