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

TL;DR: In this article, a flexible polyether dumbbell bearing 1,5-dioxynaphthalene (DNP) donors, which folds its way through a series of cyclobis(paraquat-p-phenylene) (CBPQT4+) acceptor rings in a serpentine fashion, is used to enable extended donor-acceptor (D-A) stacking between DNP and the electron-poor 4,4′-bipyridinium (BIPY2+) units.

Alumina membranes — templates for novel nanocomposites
Taka-aki Hanaoka,Andreas Heilmann,Michael Kröll,Hans-Peter Kormann,Thomas Sawitowski,Günter Schmid,Peter Jutzi,A. Klipp,Uwe Kreibig,Rolf Neuendorf +9 more
TL;DR: This paper showed that nanoporous alumina membranes serve as ideal templates for the formation of nanostructured materials and also as a support of those materials in composites, and the unique properties of such membranes (transparency, chemical resistivity, thermal stability, adjustable pore sizes etc.) and the very simple mode of generating these composites are the benefits of using this inorganic template material.

Molecular tectonics I: The first synthesis and X-ray analysis of a linear koilate obtained by self-assembly of linear koilands and hexadiyne
TL;DR: In this paper, the first synthesis and X-ray analysis of a koilate, i.e., a linear array in the solid state, resulting from an iterative assembling of a Koiland (hollow molecule possessing two divergent cavities based on the double fusion of two p-tert-butylcalix[4]arenes by two silicon atoms), and hexadiyne as connector, as well as two binuclear complexes formed in a solid state between the above mentioned koiland and anisol and para-xylene is described.

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.
