A series of double-decker silsesquioxane derivatives with four reactive functional groups were designed, efficiently synthesized, and characterized. These novel inorganic-organic hybrids show highly attractive features for applications as building blocks with Si-O-Si rigid cores (good thermal properties) with four reactive moieties, which can be functionalized in further processes. The preparation of a series of double-decker silsesquioxane (DDSQ) derivatives with four reactive functional groups (FGs) is described. The synthetic approach is based on a highly efficient functionalization of a simple tetrasilanol form of DDSQ.
