TABLE OF CONTENTS Research on nanostructured materials is an active and rapidly developing interdisciplinary field involving chemistry, physics, and biology and is related to the technological development of materials science, information science and microelectronics. During the past few years, studies in these fields such as the synthesis of nanocrystals materials or quantum dots (QDs) to construct organized assemblies on nanoscale dimensions, and the microscopic mechanisms of surface and interfacial electron transfers have made great progress. In the areas of technological interest, all will benefit significantly from multidisciplinary research. Indeed, nanostructured organized assemblies with optoelectronic functionality will play a key role in advanced materials in the next century.
From the viewpoint of physics and chemistry, the QDs building blocks with photoactive or electroactive units are considered first. In other words-nanostructured species are characterized by the nanoscale ordered arrangement of their components, such as metal or semiconductor clusters and nanocrystals, as well as supramolecular chemistry by the nature of the intermolecular noncovalent interactions that hold these components together on nanoscales to form spontaneously supramolecular chemical organized assemblies.
What is supramolecular chemistry? In his Nobel lecture, Lehn (1988, 1990) put it succinctly: "Supramolecular chemistry is the chemistry of the intermolecular bond, covering the structural and functional entity formed by association of two or more chemical species." The types of interactions may include metal ion coordination, electrostatic interactions, hydrogen bonding, and van der Waals forces, which provide new comprehensive methods for chemical assembly. The unifying power and interdisciplinary nature of supramolecular chemistry have...
