摘要：

Hydrogen silsesquioxane, (HSiO3/2)8, T8, has been synthesized and isolated in synthetically useful quantities. The T8 cage-like structure allows eight pendant groups to be placed symmetrically about the surface of a sphere to form an 'octopus' molecule. Using T8 to hydrosilylate compounds with the formula CH2=CH(X)(n)Y, octopus molecules of the formula (SiO3/2)8(CH2CH2(X)nY), have been synthesized, including octopus molecules with organic 'arms' as well as those with silicone 'arms' of various lengths. The regioselectivity of addition in the above two cases was found to differ. The synthesis of these novel octapus molecules and their characterisation by Si-29 NMR, FTIR, and gel-permeation chromatography (GPC) is described.
