摘要

本文报道了基于苯三甲酰胺和二邻位取代偶氮苯的超分子液晶（LC）材料的设计、合成和光响应行为。差示扫描量热法、偏振光学显微镜和广角x射线散射研究证实了在室温下柱状四方中间相的形成。光异构化研究揭示了化合物在溶液中的可见光响应性。此外，我们展示了超分子凝胶的形成，它在蓝光照射下经历不可逆的凝胶-溶胶转化，突出了它在光触发的药物递送、能量存储等领域的应用潜力。

Room-Temperature Columnar Tetragonal Self-Assemblies based on Benzenetricarboxamide and Di-ortho Substituted Azobenzene

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.
