Mechanistic understanding of hydrocarbon‐pool (HP) chemistry in the methanol‐to‐olefins conversion over zeolites is challenging. In their Communication on page 2507 ff., F. Deng, J. Xu, and co‐workers report the direct detection of supramolecular reaction centers, composed of organic hydrocarbon‐pool species and the inorganic zeolite framework, by solid‐state NMR spectroscopy. The interaction/proximity between the hydrocarbon‐pool species and the Brønsted acid/base sites of the zeolite determines the reactivity of the hydrocarbon‐pool species.
