Abstract: "New strategies for
materials fabrication are of fundamental importance in the advancement of
science and technology. Organometallic and other organic solution phase
synthetic routes have enabled the synthesis of functional inorganic
quantum dots or
nanocrystals. These
nanomaterials form the building blocks for new bottom-up approaches to
materials assembly for a range of uses; such materials also receive
attention because of their intrinsic size-dependent properties and resulting
applications. Here we report a unified approach to the synthesis of a large
variety of nanocrystals with different chemistries and properties and with
low dispersity; these include noble metal, magnetic/dielectric,
semiconducting, rare-earth fluorescent, biomedical, organic optoelectronic
semiconducting and conducting polymer nanoparticles. This strategy is based
on a general phase transfer and separation mechanism occurring at the
interfaces of the liquid, solid and solution phases present during the
synthesis. We believe our methodology provides a simple and convenient route
to a variety of building blocks for assembling materials with novel
structure and function in
nanotechnology."
