Tris(2,2'-bipyridyl)rutheniuin(II)with Branched Polyphenylene Shells:A Family of Charged Shape-Persistent Nanoparticles

摘要

Polyphenylene dendrimers with poly(pentaphenylben-zene)branches(PPDs)are special within dendrimer chemistry because of their stiff,mostly radial arms that do not allow backfolding,thus rendering the molecules shape-persistent.'31 As a result,their overall shapes are defined by the geometry of the particular core unit,and different cores(Figure 1 a-c)have been proven to generate structural diversity.
