POSSaxanes: active-template synthesis of organic–inorganic rotaxanes incorporating cubic silsesquioxane stoppers.

The CuAAC active-template approach was exploited to construct rotaxanes incorporating cage-like silsesquioxane stoppers, namely, POSSaxanes. The compounds were characterized in the solution and solid state, providing the unprecedented molecular structures of POSS-incorporating rotaxanes. [ABSTRACT FROM AUTHOR]
