Abstract

Siloxane-based nanoporous materials have a wide range of applications. In this study, a double-four-ring cage siloxane modified with dimethylsilanol groups at eight vertices was cross-linked via reaction with titanium(IV) tetraethoxide to construct a three-dimensional network with SiOTi bonds, producing a nanoporous material. The product exhibited catalytic activity for the liquid-phase oxidation of cyclohexene with relatively high selectivity. This building block approach opens a new route to nanoporous materials composed of fully inorganic SiOSi and SiOTi linkages.
