By precisely tuning the pore space and the geometric disposition of inorganic anions in a 0.1–0.5 Å scale for the best match of the guest size/shape, Huabin Xing and co‐workers report a fascinating trap for single propyne molecules in article number 1705374 . This trap enables extremely high propyne uptake under ultralow pressure and record selectivity, affording the efficient removal of trace propyne from propylene.
