| 摘 要： | 具有坚固、智能、且易于编程等特性的信息加密材料对于防止信息泄露和打击造假具有重要意义.为此,我们开发了一种信息加密材料工具箱,该工具箱基于一系列新型的自修复光开关双态(P1和P2)和多态(P3)荧光聚合物.这类聚合物含有两种二芳基乙烯光致变色荧光基团(SDTE和BTBA)和四重氢键构筑单元(UPy).在不同波长的光照射下,P1/P2可以在绿-猝灭/红-猝灭两态之间交替,而P3可以在红-绿-猝灭三态之间变化.它们可以作为像素单元用来制备可重构的图案和代码;所得到的图案和代码均显示出良好的机械性能和优异的光学特性,包括快速的光响应性、突出的光可逆性、优异的荧光热稳定性和抗酸碱腐蚀的能力.本文展示了该工具箱在3D代码阵列和二维码信息加密中的应用潜能.
