Preparation of Carbosilane Dendrimers with Perfluorosilane Branches

摘要

Perfluororosilanes are highly stable compound, which used in a wide range of applications to heat resistance, impermeable to chemicals, sliding properties, electric characteristics and it has been also exhibit special repellency to water. In addition, the measurement of wetting property and hydrophobic coating by the use of perfluorosilane film on metal oxide surface are widly studied. And as a related subject, dendrimers are well defined macromolecule composed a focal point, it has unified and applicable nummerous end groups. This report presents the preparation of carbosilane dendrimers having peripheral groups replaced by fluorinated functions as a characteristic peripheral branches. These dendrimers expects that show a new characteristic presisonal properties as a hydrophobic matter. Fluorinated alkyl branches having F3C(CF2)7(CH2)2O-(Heptadecafluoro-1,1,2,2-tetrahydro-1-decanoxy; HDFD) and F3C(F2)5(CH2)2O-(Tridecafluoro-1,1,2,2-tetrahydro-1-octanoxy (TDFO) functions were used.
