Abstract

Cluster

Crown ether

Luminescence

Nanoparticles

Osmium

Silver

Silver nanoparticles protected with the crown ether (6-mercaptohexyloxy)methyl-15-crown-5, or the triosmium cluster derivative Os 3(μ-H)(CO) 10[(6-mercaptohexyloxy)methyl-15-crown-5], show good stability, are soluble in a wide range of organic solvents, and are luminescent. Monolayer-protected clusters of silver have been synthesised by the NaBH 4 reduction of a mixture of silver nitrate and the crown ether (6-mercaptohexyloxy)methyl-15-crown-5, or the triosmium cluster derivative Os 3(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.
