Reports of the synthesis of new dendrimers containing organometallic fragments have increased dramatically over the past few years and examples of dendrimers containing many different metals are now known. This article highlights some of the the ways in which transition metals and their ligand systems have been incorporated into the growing number of dendrimers. Some structural details and properties of metal-containing dendrimers are described, and their applications are also discussed. The cover illustration shows Table Mountain, South Africa and a fourth generation ruthenium dendritic wedge.
