Advanced Silesquioxane Research Program

Collaborators: Goodson Group (UofM), Rand Group (UofM)
Sponsor: Department of Energy (DOE), Mayaterials
Our objective in this work is to develop synthesis-processing relationships for silsesquioxanes (SQs) [(RSiO1.5)8,10,12] materials with the goal of learning to predict, control and tailor materialsÕ properties one nanometer at a time. These materials can be made by sol-gel methods in the case of the T8, with the more thermodynamically stable T10/12 being formed by a fluoride catalyzed cage rearrangement, and represent a new frontier in materials chemistry, science and engineering because they offer the potential to develop and tailor composite materials with control at the finest length scales. Work on mono and polyfunctional silsesquioxanes suggests that these materials offer the potential to make libraries of nanoplatforms and nanobuilding blocks with diverse functional groups and thereafter highly tailored nanocomposite materials with novel properties. In particular, efforts are made to develop routes to core shell materials with multiple functionalities through the development of new ways to selectively functionalize organic components. Our work focuses on making both mixed functional and monofunctional SQ materials with functional groups that are potentially liquid crystalline, light emitting or absorbing, materials for electronic substrates with good high temperature stability, gas storage and catalysis, transparency, and that offer good film forming properties.

  • Diversity from Oligomeric Silsesquioxanes

    In collaboration with our industrial partner, Nippon Shokubai research done here mainly by Kunio Takahashi, we have been creating new Q8 and octaphenylsilsesquioxane (OPS) materials with functional groups that are potentially liquid crystalline, light emitting or absorbing and materials for electronic substrates with good high temperature stability and that offer good film forming properties. These materials are the future for flat panel screens and high efficiency lighting for household and industrial use.

  • Silsesquioxanes Nanoplatforms

    Organic/inorganic hybrid materials represent a new frontier in material chemistry, science, and engineering because they offer the potential to develop and tailor composite materials with control at the finest nanometer length scales. However, the basic problem is that well-defined with diverse functionality are difficult to obtain. Polyhedral oligomeric silsesquioxanes (POSS) offer one solution to this problem in that they provide the opportunity to design materials with extremely well-defined dimensions and behavior.
