Controlled assembly of nanosized metallodendrimers

Article abstract of DOI:10.1002/anie.199612131

Up to third-generation metallodendrimers can be constructed by a repetitive sequence of reactions with building blocks that contain two coordinatively unsaturated Pd centers ('pie' shape) and one labile, coordinating cyano group. The key steps of assembly are the displacement of the chloro ligands with AgBF₄ and the in situ reaction with the cyano groups of the dendrimer building blocks to give the next generation. The resulting dendrimers have molecular masses of up to 25 kDa.
