Self‐Assembled Cyclotriguaiacyclene‐Integrated Supramolecular Systems for Liquid Crystal and Self‐Assembly Behavior

An advanced tri‐substituted supramolecular material was synthesized via conversion of cyclotriveratrylene to cyclotriguaiacyclene with further esterification reaction with fluorescein unit embedded with side‐arms. All four luminescent materials exhibited columnar hexagonal type mesophase on both heating and cooling conditions. The materials with hexadecyloxy and octadecyloxy tail group exhibit liquid crystalline behavior at room temperature indicating the presence of a mesophase even under ambient conditions. By combining polarizing optical microscopy, differential scanning calorimetry, and high‐temperature X‐Ray diffraction techniques to understanding the optical, thermal, and molecular packing behavior of the compounds in the liquid crystalline state. The cyclotriguaiacyclene core with high fluorescent nature displayed columnar hexagonal type self‐assembly at room temperature. All four supramolecular mesogens showed higher thermal stability of mesophase. The computational study provides the importance of the electronic nature of the compounds. Columnar self‐assembly of cyclotriguaiacyclene (CTG) functionalized supramolecular systems, which are found to be driven by the formation of non‐covalent molecular interactions, result in the creation of room temperature liquid crystalline properties and self‐assembly behavior.
