An artistic representation of a new series of perylene‐centered disc tetramers that self‐assemble into room‐temperature columnar structures is shown. Although compounds with shorter alkyl spacer chain length self‐organize into soft‐crystal columnar oblique lattice, the higher one exhibits a columnar nematic phase. The compounds were green‐light emissive in solution, as well as in the thin‐film state with high quantum yields, and may act as an active component in OLEDs.
