AbstractStrategies to generate heteromeric peptidic ensembles via a social self‐sorting process are limited. Herein, we report a crystal packing‐inspired social self‐sorting strategy broadly applicable to diverse types of H‐bonded peptidic frameworks. Specifically, a crystal structure of H‐bonded alkyl chain‐appended monopeptides reveals an inter‐chain separation distance of 4.8 Å dictated by the H‐bonded amide groups, which is larger than 4.1 Å separation distance desired by the tightly packed straight alkyl chains. This incompatibility results in loosely packed alkyl chains, prompting us to investigate and validate the feasibility of applying bulky tert‐butyl groups, modified with an anion‐binding group, to alternatively interpenetrate the straight alkyl chains, modified with a crown ether group. Structurally, this social self‐sorting approach generates highly stable hetero‐oligomeric ensembles, having alternated anion‐ and cation‐binding units vertically aligned to the same side. Functionally, these hetero‐oligomeric ensembles promote transmembrane transport of cations, anions and more interestingly zwitterionic species such as amino acids.
