Stacks of macrocyclic molecules are interesting entities for materials applications, which can provide nanopores created by aligned macrocyclic openings. Among a series of chiral naphthylene macrocycles, [ n ]cyclo‐ epi ‐naphthylenes ([ n ]CeNAPs), synthesized in this study, a congener with 8 naphthylene panels ([8]CeNAP) formed robust columnar assemblies in crystals. The chiral nanopores captured gaseous N 2 molecules by providing ten accommodation sites for the N 2 molecules with one macrocycle, and six stacking pairs of enantiomeric N 2 molecules were revealed by in‐situ synchrotron X‐ray diffraction analyses.
