Abstract Porous materials with open metal sites have been investigated to separate various gas mixtures. However, show the limitation in separation of some challenging mixtures, such as C 2 H /CO . Herein, we propose a new type ultra‐strong nano‐trap based on multiple binding interactions efficiently capture molecules and mixture. The acetylene shows benchmark Q st 79.1 kJ mol −1 for , record high pure uptake 2.54 mmol g at 1×10 −2 bar, highest selectivity (53.6), making it material locations within MOF‐based nanotrap visualized by situ single‐crystal X‐ray diffraction studies, which also identify accountable strong
