Abstract Sol-gel polymerization of [Si8O12](OCH3)8 in an inert solvent under neutral conditions has been shown to yield very high-surface area silica xerogels [P. C. Cagleet al., Mater. Res. Soc. Symp. Proc. 180, 29 (1990)]. Two recent results relevant to this process are described here. First, a practical synthetic route to [Si8O12](OCH3)8 is described that allows multigram quantities to be conveniently prepared. Second, TEM studies are reported that confirm retention of the [Si8O12] cubic core structure in high-surface area, [Si8O12](OCH3)8 − derived xerogels.
