Precise control of the porosity of silica‐based hybrid materials is the topic discussed here. One approach in particular—the copolycondensation of two precursors followed by selective removal of one of the organic spacers (see Figure) —is highlighted. Using this technique, microporous hybrid xerogels are produced that have a high specific surface area and a highly hydrophobic surface.
