“…In the early days of dendrimer chemistry, molecular characterization was carried out in most cases by 1 H, 13 C, and 29 Si NMR spectroscopy as well as size exclusion chromatography (SEC). However, in higher generations the differences between the relative intensities of the signals of the perfect structure and those of the imperfect structure are too marginal to be detected.…”

Summary. This micro-review summarizes historical and recent developments in synthesis, functionalization, and characterization of carbosilane dendrimers. These compounds are the most important among the heteroatom-based dendrimers at present due to the flexibility of the synthetic route and to their chemical stability which allows versatile further functionalization. Synthesis as well as application potential of carbosilane dendrimers for catalysis, host-guest chemistry, liquid crystals, and novel polymer topologies is discussed.Keywords. Carbosilane; Dendrimer; Catalysis; Liquid crystals; Hyperbranched.Carbosilandendrimere -Synthese, Funktionalisierung und Anwendung Zusammenfassung. Der vorliegende Mikroreview faSt historische und aktuelle Entwicklungen bezuglich Synthese, Funktionalisierung und Charakterisierung von Carbosilandendrimeren zusammen. Wegen der Variabilitat der Syntheseroute und ihrer chemischen Stabilitat, die weitere Funktionalisierung erlaubt, zahlen diese Verbindungen zu den wichtigsten unter den Heteroatomdendrimeren. Synthese und Potential der Carbosilandendrimere auf den Gebieten der Katalyse, Wirt-Gast-Chemie, Flussigkristalle und neuer Polymertopologien werden diskutiert.

Upon being discovered 20 years ago, sodiumoxyorganoalkoxysilanes became the key to the world of organoelement dendrimers. Even considering the great variety of objects that had appeared in this area during the last 20 years, the organosilicon dendrimers are still one of the most actual objects in this class. Above all, this is fair concerning the carbosilane systems. The high reactivity of the functional groups, the well controlled chemistry of their transformations, and the inertness of the molecular skeleton are the reason for making these systems highly actual in two main regards: as model objects for the deep research of the dendrimers' properties and as polyfunctional matrixes for numerous derivatives. In this review, we were mainly focusing on the importance of the former part. In the conclusion, we showed the motivation for further development of this area both in regard of synthesis of new carbosilane systems and further development of siloxane dendrimers.

“…The method is based on a hydrosilylation-deprotection sequence allowing the purification of the dendritic structure prior to the unmasking of the hydroxy functionality. The disclosure of these results is prompted by the recent publication of conceptually related procedures performed on allyl [15] and vinyl [16] dendritic silanes.…”

The synthesis and characterization of a series of four-, eight-, 16-, and 32-arm carbosilane dendrimers are reported. The four-arm dendrimer was synthesized via the reaction of silicon tetrachloride with a primary organomagnesium compound. The other dendrimers were obtained through an efficient hydrosilylation of polyolefinic dendritic cores with functionalized alkylhydrosilanes. The latter reaction holds promise for the synthesis of larger generation carbosilanes with various hydrophilic end-groups. These compounds should find use as multifunctional anionic initiators for the synthesis of dendrimer-polymer hybrids.
