Luminescent silver nanoparticles stabilised by a crown ether capped with an organometallic cluster

Abstract

Monolayer-protected clusters of silver have been synthesised by the NaBH4 reduction of a mixture of silver nitrate and the crown ether (6-mercaptohexyloxy)methyl-15-crown-5, or the triosmium cluster derivative Os3(μ-H)(CO)10[(6-mercaptohexyloxy)methyl-15-crown-5]. The nanoparticles showed good stability, are soluble in a wide range of organic solvents, and are luminescent. © 2007 Elsevier B.V. All rights reserved.
