Room‐Temperature Columnar Tetragonal Self‐Assemblies based on Benzenetricarboxamide and Di‐<i>ortho</i> Substituted Azobenzene

Abstract Here we report the design, synthesis, and photoresponsive behavior of supramolecular liquid crystalline (LC) materials based on benzenetricarboxamide and di‐ ortho substituted azobenzene. Differential scanning calorimetry, polarized optical microscopy, and wide‐angle X‐ray scattering studies confirm the formation of columnar tetragonal mesophase at room‐temperature. Photoisomerization studies reveal the visible light responsiveness of compounds in solution. Furthermore, we demonstrate supramolecular gel formation, which undergoes irreversible gel‐sol transformation upon blue light irradiation, highlighting its potential for light‐triggered applications in the field of drug delivery, energy storage etc.
