Abstract
Abstract We demonstrate the utilization of cage germoxanes as templates for tuning the pore characteristics of siloxane-based materials. Molecular-scale composites of cage germoxanes and cage siloxanes were prepared by hydrosilylation reactions between SiH- and vinyl-modified cage siloxanes in the presence of vinyl-modified cage germoxanes. Subsequent acid treatments selectively removed the germoxane moiety, resulting in variation in the pore structures. These results contribute to developing a novel method for tuning the pore characteristics of siloxane-based nanoporous materials.
