Spiropyran-Based Columnar Liquid Crystals

Spiropyran-Based Liquid Crystals: The Formation of Columnar Phases via Acid-Induced Spiro-Merocyanine Isomerisation, Chem. Commun., 2006, 4703-4705.

Hexagonal columnar liquid-crystalline phases are induced for a new fan-shaped spiropyran compound as the result of an acidichromism effect of spiro-merocyanine isomerisation through protonation upon incorporation of 4-methylbenzene sulfonic acid.
