Abstract Separating propyne/propadiene to produce pure propadiene is extremely challenging in industry due their similar properties. Herein, a novel ZrF 6 2− anion pillared cage‐like metal‐organic framework (termed as CuZrF ‐TPA) for highly efficient separation reported. It exhibits high propyne capacity (177.4/188.6 cm 3 /cm at 0.5/1.0 bar and 298 K), benchmark selectivity (6.0), remarkable potential (5.7 mol L −1 ) simultaneously. Record productivity (≈4.7 achieved through single adsorption process breakthrough experiments with excellent recycle stability even under humid conditions. Based on the structure of propyne‐loaded crystals, two binding sites are identified, including major trapping site windows minor located large cages. Modelling studies further confirm that contracted cage surrounded rotating Lewis basic F atoms aromatic rings optimal bonding capture multiple hydrogen π···π interactions.

Abstract Layer‐stacking behaviors are crucial for two‐dimensional covalent organic frameworks (2D COFs) to define their pore structure, physicochemical properties, and functional output. So far, fine control over the stacking mode without complex procedures remains a grand challenge. Herein, we proposed “key‐cylinder lock mimic” strategy synthesize 2D COFs with tunable layer‐stacking by taking advantage of ionic liquids (ILs). The staggered (AB) (unlocked) were exclusively obtained incorporating ILs symmetric polarity matching molecular size; otherwise, commonly reported eclipsed (AA) (locked) observed instead. Mechanistic study revealed that AB was induced confined interlocking effect (CIE) brought anions bulky cations inside pores (“key” “cylinder”, respectively). Excitingly, this can speed up production rate crystalline powders (e.g., COF‐TAPT‐Tf@BmimTf 2 N in merely 30 minutes) under mild reaction conditions. This work highlights enabling role tailor layer promotes further exploration mode‐dependant applications.
