Mesoporous polysilsesquioxanes: Preparation, properties, and applications

Research output: Chapter in Book/Report/Conference proceedingChapter


Mesoporous polysilsesquioxanes are an important class of hybrid organicinorganic materials with numerous applications in microelectronics, membranes, chromatographic materials, catalysis, and more. Prepared by sol-gel polymerization of monomers with trialkoxysilyl groups, these materials are based on siloxane networks modified by organic groups. Mesoporosity in these materials is formed through sol-gel polymerizations by themselves or can be directed into ordered arrays using surfactant templating. Surfactant templating allows mesopores in geometries ranging from cylindrical pores to gyroid porosities. Surfactant templating also enables the facile development of hierarchical structures where multiple modes of pores can independently coexist in the same material. Formulations for preparation of all of these mesoporous materials as monoliths, particles, and coatings will be discussed and examples will be provided.
