Dispersion‐Clamped Crystalline Supramolecular Columnar π‐Stacks of Adamantyl‐Substituted Pyrenes

open access: yesAngewandte Chemie, EarlyView.
Can neutral hydrocarbon π‐systems be forced into perfectly aligned cofacial stacks in crystals? An adamantyl‐decorated pyrene derivative crystallizes into rare translationally zero‐offset π‐columns, producing a short π–π distance below 3.3 Å and a large color shift arising from frontier crystal orbital (FCO) formation. ABSTRACT Despite their importance
