Selective functionalization of the internal and external surfaces of MCM‐41 silica has been achieved using a topochemical molecular engineering approach. Functionalization is carried out in a stepwise process, the groups becoming selectively attached via silane coupling reactions and through use of a template to produce a structure with external trimethysilyl groups and internal aryl groups (see Figure).
