“…48 Two terminal hydrophilic groups of different size glucopyranose and carboxylic acid headgroups were covalently linked to an oligomethylene spacer (carbon numbers ¼ 12À20). Self-assembled organic nanotubes from 1(14), 1(16), 1 (18), and 1 (20) possess inner diameters in the 17.7À22.2 nm range at intervals of $1.5 nm, with an increment of two carbons in the spacer chains (Fig. 5).…”

“…Recently, supramolecular chemical procedure enabled the self-assembly of graphitic nanotubes from hexabenzocoronene amphiphiles derivatized from a partial section of graphene. 20 Those nanotubes are of great interest in terms of possibly sharing the properties of CNT and LNT. [24][25][26] …”

“…Confined liquid nanospace shaped by a LNT should be favorable to feature the chemical events in attoliter volume, which is associated with ''attoliter chemistry.'' Self-assembled nanotube architectures from diverse organic molecules including proteins, 17 DNA, 18 synthetic polymers, 19,20 and amphiphiles (lipids) 15 have recently been developed in large numbers. They are gradually demonstrating attractive potential for practical use in different fields from those related to carbon nanotubes.…”

Diverse chemical functionalization of the inner and outer surfaces of the nanotubes enables us to sense and visualize the encapsulation and transport behavior of biomacromolecular guests. The event occurs specifically in attoliter volume nanospace inside the hollow cylinder of the nanotubes. Comparison of the organic nanotube history with that of well‐known carbon nanotubes and a variety of molecular building blocks as tube‐forming compounds were first introduced. Asymmetric organic nanotubes with different inner and outer surfaces were discussed in terms of molecular design, immobilization of functional moieties, and molecular packing. Finally, the practical examples of the organic nanotubes as a nanocontainer, nanochannel, and nanopipette were also described to feature the concept of “attoliter chemistry.” © 2008 Wiley Periodicals, Inc.

“…Aida and co-workers 55 showed that amphiphilic HBCs (having a mini Janus plane, Figure 4a) have distinctly different assembly properties than HBCs with any other substitution pattern. Specifically, HBCs bearing two pseudo-cis alkyl chains and two pseudo-cis TEG chains selfassemble into hollow nanotubes by p-stacking in tetrahydrofuran.…”

Harnessing synthetic power to create novel materials with unique assembly properties is of fundamental interest for pushing the limits of molecular and macromolecular assembly, while further holding the potential for improving electronic and medical device performance. Controlling the assembly of aromatic molecules into nanostructures provides routes towards continuous and extended structures with performance that is improved markedly over that of their individual molecular components, opening possibilities for the formation of composites that have tailored interactions with other materials and thus improved applications. This review covers recent advances in the synthesis of conjugated materials, their controlled assembly into nanoscale architectures and implementation into devices. Specifically, we discuss the solution-based assembly of polythiophene into nanowire fibrils, the formation of columnar stacks of hexabenzocoronene liquid crystals and the preparation of functionalized solution processible graphene for nanocomposite formation.

“…[6][7][8][9][10] Controlled ordering of the self-assembled architectures requires skillful design of molecular constituents. Successful examples are spherical to tubular or cylindrical assemblies formed by attaching chiral handles 11,5,[12][13][14][15][16] or by the sergeant-and-soldiers [17][18][19][20] coassembly approach. More recently, a rare transition from vesicles to helical tubules has been obtained by sergeant-and-soldiers coassembly of chiral and achiral oligo(p-phenylene-ethynylene) derivatives.…”

Chiral rod-coil-type organoboron polymers S-poly and R-poly were prepared from the palladium-catalyzed SonogashiraHagihara coupling reaction of boron dipyrromethene-based monomer 1, which has bisiodophenyl and decyl groups with S-or R-6,6¢-diethynyl-2,2¢-dioctyloxy-1,1¢-binaphthyls (S-2 and R-2), in a solvent mixture (tetrahydrofuran (THF)/triethylamine¼2/1 (v/v)) at 40 1C for 24 h. The obtained polymers were characterized by hydrogen-1 nuclear magnetic resonance (NMR), carbon-13 NMR ( 13 C NMR), boron-11 NMR ( 11 B NMR) and infrared spectroscopy. The scanning electron microscopy (SEM) analysis of each chiral polymer clearly revealed micrometer-sized fiber-like structures formed by the aggregation of each particle, as we expected. Next, we examined the relationship between the ratio of photoluminescence (PL) intensity (I/I 0 ¼R-poly/S-poly) and particle diameter, measured by dynamic light scattering analysis, versus the R-poly content of the mixed polymer of S-poly and R-poly in THF, which varied from 0 to 100%. As a result, the PL intensity and diameter showed maximum and minimum (about 32 nm) values, respectively, at 70% content, depending on the differences between both the molecular weights and absolute values of the chiral characters. These findings indicate that the PL intensity of S-poly influences morphology change by adding R-poly; that is, R-poly acts as an inhibitor toward the aggregation of S-poly. Furthermore, the SEM image of the mixed polymer (S-poly/R-poly¼30/70) showed complete particle structures from nano-to micrometer sizes, which were roughly 480 nm to 1.19 lm in diameter, and the U F of the mixed polymer was significantly high (0.98).
