Metallodendrimers containing both ruthenium (internal layer) and rhenium (external layer)†
Abstract
The reaction of [Re(bipy)(CO)3(CCpy)] with two carbosilane dendrimers containing terminal (p-cymene)Ru(triflate)2 units gives bimetallic dendrimers functionalised with (p-cymene)Ru(triflate)(pyCC)Re(bipy)(CO)3 units. Dendrimers of this kind can be envisaged as formed by two metal layers: the internal, constituted by ruthenium atoms, and the external, by rhenium metals. The luminescent properties of these species are only attributed to the rhenium moieties.
