Mesoporous silicates have found use as templates for the creation of organic-inorganic nanocomposites. However, a limiting factor has been the fraction of organic material that could be linked to the silicate backbone without destroying the mesoporosity. Landskron et al. (p. 266) have found a route to form rings of alternating Si and CH2 groups to create a periodic mesoporous material with a much higher organic fraction. Films of this material have both a low dielectric constant and high mechanical stability and thus may find use in microelectronics.
