摘要
具有高敏感刺激响应荧光变色薄膜材料在智能传感器和光学加密等领域应用广泛。然而相比于光致变色材料而言,光致荧光变色材料的研究和发展仍非常有限。在本工作中,我们在聚乙烯醇主体中引入客体二苯乙烯类发光材料,开发出新型的自支撑纳米纤维薄膜。这类薄膜材料表现出快速、明显的光致荧光变色特性,并且两个荧光颜色之间很容易发生可逆转换。这项基于实验和理论相结合的研究工作不仅提供了新型光诱导荧光变色二苯乙烯掺杂聚合物复合材料,也详细探究了纳米纤维的光异构化过程。这类光致荧光变色薄膜材料可应用于可擦式存储器设备和防伪领域。
Highly sensitive stimuli-responsive fluorescent films play an important role in smart sensors and readable optical devices. However, systems involving light-driven fluorescence changes are still limited compared with photo-chromic materials. Herein, by incorporation of stilbene-based molecules into a poly(vinyl alcohol) host, we have developed new flexible self-supporting nanofiber films that exhibited fast and obvious photochromic fluorescence(PCF). The reversible transfer can be easily recycled. Based on the combination of experimental and theoretical studies, this work not only supplies new stilbene-based systems with light- induced fluorescence change, but also gives detailed understanding on the photoisomerization and PCF processes of the nanofibers systems. We anticipate that these PCF films can be applied in erasable memory devices and antiforgery materials.
