Flavylium Salts: A Blooming Core for Bioinspired Ionic Liquid Crystals.

ABSTRACT: Thermotropic ionic liquid crystals based on the flavylium scaffold have been synthesized and studied for their structure-properties relationship for the first time. The mesogens were probed by differential scanning calorimetry (DSC), polarizing optical microscopy (POM), and X-ray diffraction (XRD). Low numbers of alkoxy side chains resulted in smectic (SmA) and lamello-columnar (Lam_Col ) phases, whereas higher substituted flavylium salts showed Col_ro as well as ordered and disordered columnar (Col_ho , Col_hd ) mesophases. Mesophase width ranged from 13 K to 220 K, giving access to room temperature liquid crystals. The optical properties of the synthesized compounds were probed towards absorption and emission properties. Strong absorption with maxi
