Like sucking and chewing sweets the action of sodium hydroxide leads to clathrasil nanocrystals by selective silicon dissolution. In the Communication on page 7913 ff., Pérez‐Ramírez et al. show that the size, porosity, and composition of octadecasil crystals can be tuned by adjusting the alkaline conditions. This top‐down approach could lead to functional clathrasils, opening a new window for research on this type of materials both in terms of post‐synthesis modification and application in catalysis.
