Abstract

Trimethylsilylation of a triethoxysilylated derivative of double-four-ring (D4R) silicate led to the formation of a novel crystalline spherical siloxane molecule containing a cubic D4R core, which proves that this bottom-up process provides a new pathway to prepare silica nanoparticles with well defined size, structure, morphology, and functionality.
