Synthesis of carbosilane dendrimers based on tetrakis(phenylethynyl)silane

Carbosilane dendrimers of first to third generation were synthesized, using alkynylation/hydrosilation cycles with lithium phenylacetylide and dichloromethylsilane as building blocks and tetrakis(phenylethynyl)silane as a core molecule. The analysis of the 1H- and 13C-NMR, MALDI mass spectra and elemental analysis made it possible to obtain pure and unified dendrimers.
