Titanosilsesquioxanes Embedded in Synthetic Clay as a Hybrid Material for Polymer Science

摘要

Polyhedral oligomeric silsesquioxanes (POSSs) are attracting growing interest in catalysis and materials science. Metal centers in their silica framework show catalytic properties, and POSS cages have been used as building blocks for multifunctional composite solids and for hierarchical inorganic/organic hybrid architectures. This success is due to the versatility of these compounds, which may include almost inert hydrocarbon moieties (R), reactive groups, and metal centers, which can be exploited to catalyze different organic reactions, in the same skeleton (Figure 1).
