Functionalization of monovinyl substituted octasilsesquioxane via photochemical thiol-ene reaction

摘要: Abstract In this paper, monovinyl substituted POSS was chosen as the starting material to react with a series of thiols bearing hydroxyl, carboxyl, ester and trialkoxysilane groups produce corresponding functionalized monomers in high yield via thiol-ene reaction under UV irradiation. The resulting functional cage compounds were fully characterized by FTIR, NMR, elemental analysis mass spectroscopy. It appeared that more efficient synthetic strategy preparation relative methods previously explored. These enrich silsesquioxane pool they would play important roles hybrid materials other applications.
