Synthesis and properties of fluorinated derivatives of carbosilane dendrimers of high generations

Abstract

Fluorinated derivatives containing different amounts of fluorocarbon groups in the surface layer of the molecular structure have been synthesized by the chemical modification of a polyallylcarbosilane dendrimer of the sixth generation via hydrosilylation and heterofunctional condensation procedures. The fluorocontaining dendrimers are well soluble in organic solvents and supercritical CO2. Their properties have been studied by DSC, viscometry, dynamic light scattering, and atomic force microscopy.
