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.read more

Shape selection in chiral ribbons: from seed pods to supramolecular assemblies
TL;DR: The model is based on incompatible elasticity and uses dimensionless parameters to determine the equilibrium configurations of chemical systems that self-assemble into chiral ribbon structures and provides universal curves for the shape and energy of self-assembled ribbons.

Towards Complex Matter: Supramolecular Chemistry and Self-organization
TL;DR: Supramolecular entities as well as molecules containing reversible bonds are able to undergo a continuous change in constitution by reorganization and exchange of building blocks, which defines a Constitutional Dynamic Chemistry (CDC), which introduces a paradigm shift with respect to constitutionally static chemistry.

Molecular basis of cooperativity in pH-triggered supramolecular self-assembly
TL;DR: The molecular pathway of pH-triggered supramolecular self-assembly of a series of ultra-pH sensitive (UPS) block copolymers is elucidated and hydrophobic micellization and resulting positive cooperativity offer a versatile strategy to convert responsive nanomaterials into binary on/off switchable systems for chemical and biological sensing.

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.
