Cage octasilsesquioxanes denoted as (RSiO1.5)8 or labeled T8 cages are promising building blocks for organic-inorganic hybrid materials. Polymers incorporating the cage octasilsesquioxanes in their main chains are expected to possess significantly improved hydrophobicity as well as significantly reduced dynamics of the polymer segments. In comparison with polymers containing the cage silsesquioxanes in the side-chain, however, few papers have been reported the synthesis of the polymers with the cage silsesquioxanes in the main chain. This review focuses on our recent efforts to prepare main-chain type element-block polymers based on well-defined T8 cage monomers having two polymerizable functional groups. Several their unique properties and application are described.
