Spheres‐on‐sphere (SOS) silica particles are prepared in a one‐pot scalable synthesis from mercaptopropyltrimethoxysilane with hydrophilic polymer and cationic surfactant under alkaline conditions. The SOS particles exhibit solid‐core porous‐shell properties. The fast separation of small molecules and proteins with low back pressure are demonstrated by high‐performance liquid chromatography (HPLC)...
Macroscopic inorganic porous beads are imbibed with a “porous molecular additive” by simple solution processing techniques, resulting in controllable loading and increased surface area. The porous additive consists of soluble organic cage molecules that precipitate as microporous crystals when solutions of opposite chirality are mixed.
