Self Assembly of Shape Controlled Colloidal Nanocrystals (SA-NANO) - Publishable Executive Summary

Project ID: 13698
Funded under: FP6-NMP

Abstract

SA-NANO aims to achieve control and understanding of self assembly of shape controlled colloidal nanocrystals (NCs). NCs have been widely developed during the last decade and already applications in diverse technological fields have been demonstrated, such as light-emitting diodes (LEDs), biological tagging, sensing, photovoltaics, electronics, and catalysis. Recently, new synthetic methods were developed for growing NCs with elaborate shapes such as rods and tetrapods. Rods and tetrapods, generally termed as 'shape controlled nanocrystals', with diameters in the range of 2-10 nm and lengths spanning 10-100 nm, are the focus of this project. We know that only a self assembly approach is going to be applicable to create complex systems with millions or even billions of nano-components, and this is where the project will make a significant contribution. Such assemblies, which are being developed in the SA-NANO project, are interesting both in basic research, as they present a new platform on chemical and physical interactions of proximal nanocrystals, and for practical applications as they pave the way to new materials and to new functional devices. The specific S&T objectives of the SA-NANO STREP project are:
The synthesis of a new generation of shape- and composition- controlled nanocrystals with specific recognition elements and their surface functionalization
The self assembly of shape-controlled nanocrystals in solution to form chains, propellers and threedimensional structures of rods and tetrapods
The preparation of substrates patterned with nanocrystal templates of several materials as anchoring points, and assembly of shape-controlled nanocrystals on such substrates
The realization of aligned assemblies of nanorods
The study of proximity effects on the electronic & optical properties of shape controlled NCs
Theory and modeling of self assembly of shape-controlled nanocrystals
