The co‐existence of high‐density open metal sites and electronegative sites in confined ultramicropores is a big challenge. In their Communication on page 18927, D. Zhao et al. demonstrate that such sites co‐existing in ultramicroporous channels of a metal–organic framework can synergistically interact with acetylene, leading to excellent capture performance in the removal of trace acetylene from ethylene.
