Bridged-polysilsesquioxane

Bridged polysilsesquioxanes having covalently bound acidic groups, introduced via modification of the disulfide linkages within the network, were studied as solid-state electrolytes for proton-exchange fuel cell applications.473 Also, short-chain polysiloxanes with oligoethylene glycol side chains, doped with lithium salts, were studied as polymer electrolytes for lithium batteries.

A new class of hydride organic/silica compounds such as organically bridged polysilsesquioxanes 213 were prepared from the hydrolysis and condensation of triethoxysilanes 212 linked by a hydrocarbon spacer, as shown in Equation (41).
