The shape selectivity of zeolites toward guest molecules can be controlled by “grafting” organometallic compounds at the entrances to the pores on the surface and thus reducing the size of the pores in a defined way. For example, the adsorption capacity of a mordenite for isooctane is nearly lost upon reaction with dineopentylmagnesium, whereas its capacity for n‐hexane decreases only slightly. Zeolites modified in this way can react still further: for example, oxide coatings can be generated.
