Self-assembled silver nanoprisms monolayers at the liquid/liquid interface

Abstract

A crown ether derivative (4'-aminobenzo-15-crown-5 hydrotetrafluoroborate) can mediate the self-assembly of silver nanoprisms at the liquid/liquid interface in the form of a stable hybrid nanocomposite film. The metallic luster of the interfacial film results from the electronic coupling of Ag nanoprisms, suggesting the formation of closely packed nanoprism thin films. The interfacial film of nanoprisms could be transferred to solid substrates as a Langmuir-Blodgett film. The properties of films were studied by UV-vis spectroscopy and transmission electron microscopy. (c) 2005 Elsevier B.V. All rights reserved.
