Molecular self-assembly and nanochemistry: A chemical strategy for the synthesis of nanostructures

TLDR
In this article, self-assembly is defined as the spontaneous association of molecules under equilibrium conditions into stable, structurally well-defined aggregates joined by noncovalent bonds.
Abstract
Molecular self-assembly is the spontaneous association of molecules under equilibrium conditions into stable, structurally well-defined aggregates joined by noncovalent bonds. Molecular self-assembly is ubiquitous in biological systems and underlies the formation of a wide variety of complex biological structures. Understanding self-assembly and the associated noncovalent interactions that connect complementary interacting molecular surfaces in biological aggregates is a central concern in structural biochemistry. Self-assembly is also emerging as a new strategy in chemical synthesis, with the potential of generating nonbiological structures with dimensions of 1 to 10(2) nanometers (with molecular weights of 10(4) to 10(10) daltons). Structures in the upper part of this range of sizes are presently inaccessible through chemical synthesis, and the ability to prepare them would open a route to structures comparable in size (and perhaps complementary in function) to those that can be prepared by microlithography and other techniques of microfabrication.

In-situ construction of 2D direct Z-scheme g-C3N4/g-C3N4 homojunction with high photocatalytic activity

TL;DR: In this paper, a bottom-up approach was used to construct 2D g-C3N4/g-C 3N4 Z-scheme homojunction by using a bottomup approach, during which the supramolecular complex is initially formed, followed by a facile thermal polycondensation.

Exceptional adhesive and gelling properties of fibrous nanoscopic tapes of self-assembled bipolar urethane amides of L-phenylalanine

TL;DR: In this article, seven L-phenylalanine based alkyl (monopolar) and alkanediyl (bipolar) derivatives are synthesized; while the bipolar urethane amides form gels and show strong adhesive properties, the monopolar analogues form fibrous nanoscopic cloth-like tapes.

Multilayer films of cationic graphene-polyelectrolytes and anionic graphene-polyelectrolytes fabricated using layer-by-layer self-assembly

TL;DR: In this paper, new thin film composites were created using layer-by-layer assembly of polymer-coated graphitic nanoplatelets, and the positive and negative polyelectrolytes used to cover graphene sheets were poly allylamine hydrochloride (PAH) and poly sodium 4-styrenesulfonate (PSS), respectively.

Self-assembly of hydrogen-bonded supramolecular strands from complementary melamine and barbiturate components with chiral selection

TL;DR: In this paper, the triamino triazines 1 and 6 with the complementary barbiturate 7 were used for molecular recognition directed self-assembly in solution and in the solid state, and the cocrystallization of enantiomerically pure 1 or 2 with 7 leads to the formation of supramolecular strands.

Fabrication of novel biomaterials through molecular self-assembly.

TL;DR: Two complementary strategies can be used in the fabrication of molecular biomaterials as discussed by the authors : chemical complementarity and structural compatibility, both of which confer the weak and noncovalent interactions that bind building blocks together during self-assembly.
