Induction of Liquid Crystallinity by Self‐Assembled Molecular Boxes

Gut gestapelt: Helicale columnare Architekturen entstehen in einer hierarchischen Selbstorganisation unter Beteiligung von H‐Brücken, π‐π‐ und Ion‐Dipol‐Wechselwirkungen (siehe Bild). Die strategische Kombination dieser supramolekularen Wechselwirkungen in mesomorphen Systemen liefert Materialien, bei denen photoinduzierte Chiralität und der Einbau von Ionen genutzt werden können, um multifunktionelle Flüssigkristalle zu entwerfen.

Making a stack: Helical columnar architectures are prepared by a hierarchical self‐assembly process involving H‐bonding, π–π, and ion–dipole interactions (see picture). The strategic combination of these supramolecular interactions within mesomorphic systems yields materials in which photoinduced chirality and the incorporation of ions can be used to design multifunctional liquid crystals.

Spiropyran (SP), which can respond to acid, ultraviolet irradiation, and mechanical force, has received great attention as a classic molecule for the construction of stimuli-responsive materials. However, the self-assembly behavior of SP with a tunable morphology has rarely been investigated. In the present work, a SP derivative bearing two carboxyl groups and one hydroxyl group was prepared and used as a model to investigate the optical properties, molecular self-assembly, and morphology of SP. This pH-responsive derivative could undergo a large morphology variation from a sphere- to a rodlike structure by adjusting the acidity. The indoline and pyridopyran fragments contributed to π-π stacking, whereas the carboxyl groups contributed to hydrogen bonding. Both π-π stacking and hydrogen bonding contributed to the pH-responsive self-assembly. The morphologies of spiropyran aggregates formed under different conditions were characterized by SEM, TEM, and FTIR spectroscopy. Control of the morphology of the spiropyran nanostructure was achieved.
