Polyanionic Carbosilane and Carbosiloxane Metallodendrimers

Article: Polyanionic Carbosilane and Carbosiloxane Metallodendrimers Based on Cobaltabisdicarbollide Derivatives

Carbosilane and carbosiloxane metallodendrimers that contain one, four, and eight peripheral cobaltabisdicarbollide derivatives have been synthesized using regiospecific hydrosilylation of vinyl-terminated dendrimers with Cs[1,1′-μ-SiMeH-3,3′-Co(1,2-C₂B₉H₁₀)₂]

3rd Generation Carbosilane Metallodendrimer

1st Generation Carbosiloxane Metallodendrimer

Notes:

1. Skeletal ciclocarbosiloxane/carbosilane dendrimers is geometry optimized with PM6 semiempirical method Mopac2007.
2. Cobalbisdicarbollide anions are apart optimized with DFT methods B3LYP/6-311G(d,p) Gaussian03
3. Povray file is generated with Gabedit
