Controlling molecular self-organization: formation of nanometer-scale spheres and tubules
TL;DR: Crystallographic studies revealed how metal ion coordination and substrate recognition direct the formation of these supramolecular assemblies, and the addition of greater amounts of pyridine N-oxide changed the curvature of the assembling surface and resulted in theformation of extended tubules.

Abstract: Amphiphilic polyhedron-shaped p-sulfonatocalix[4]arene building blocks, which have been previously shown to assemble into bilayers in an antiparallel fashion, have been assembled in a parallel alignment into spherical and helical tubular structures by the addition of pyridine N-oxide and lanthanide ions Crystallographic studies revealed how metal ion coordination and substrate recognition direct the formation of these supramolecular assemblies The addition of greater amounts of pyridine N-oxide changed the curvature of the assembling surface and resulted in the formation of extended tubules

Ordered mesoporous molecular sieves synthesized by a liquid-crystal template mechanism
TL;DR: In this paper, the synthesis of mesoporous inorganic solids from calcination of aluminosilicate gels in the presence of surfactants is described, in which the silicate material forms inorganic walls between ordered surfactant micelles.

Molecular self-assembly and nanochemistry: a chemical strategy for the synthesis of nanostructures.
TL;DR: The ability to prepare structures in the upper part of this range of sizes 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.
