Precise Synthesis of Organometallic Dendrimers

1Introduction Dendrimers possessing a regularly branched architecture and large spherical dimensions have attracted significant attention because of their unique and tunable properties as well as their potential applications. The incorporation of organometallic species into dendritic molecules has been attracting much attention, because the addition of properties characteristic of organometallic complexes, such as magnetic, electronic, and photo-optical properties, as well as reactivity may lead to the realization of new functionalized dendrimers. Although there are many examples of organometallic dendrimers that contain metallic species at the core or at the periphery, dendrimers composed of organometallic complexes in each generation are still limited. We present here convergent and divergent approaches to novel organometallic dendrimers, of which the skeletons were built up with platinum-acetylide units.
