| 偶氮苯光致变色材料因其可逆光致异构化引起的吸收与结构变化,在可调结构色与信息显示领域展现出独特优势。本文综述了偶氮苯光响应体系在结构色调控与可重写光学信息存储方面的研究进展,重点从分子光异构机理出发,总结其在聚合物薄膜、胆甾相液晶及光子晶体等体系中的构筑策略与光学响应机制。进一步讨论了基于这些体系实现的可重写纸张、多刺激响应显示、信息存储与织物变色等应用功能。最后,对光致变色偶氮苯材料在耐久性提升、柔性可穿戴器件集成等方面的发展方向进行了展望,以期为新型可持续光学信息显示与智能光子材料的设计提供参考。 |
| 英文摘要: |
| Azobenzene photochromic materials exhibit unique advantages in tunable structural coloration and information display owing to the reversible changes in absorption and structure induced by photoisomerization. This review summarizes recent advances in azobenzene photoresponsive systems for structural color modulation and rewritable optical information storage. Starting from the molecular photoisomerization mechanism, the construction strategies and optical response mechanisms of polymer films, cholesteric liquid crystals, and photonic crystal systems are discussed. Furthermore, applications based on these systems are highlighted, including rewritable paper, multi-stimuli-responsive displays, information storage, and color-changing textiles. Finally, future perspectives on improving durability and integrating photochromic azobenzene materials into flexible wearable devices are presented, aiming to provide guidance for the development of sustainable optical information display technologies and intelligent photonic materials. |
