Abstract

Smart persistent organic room-temperature phosphorescence (RTP) materials, capable of responding to microenvironmental changes, are critically important in various optoelectronic applications. However, conventional persistent RTP materials usually have not stretchability and flexibility, limiting some practical applications. This study reports a facile and one-pot photo-initiated copolymerization method to prepare photoactivated persistent RTP polymers with multicolored afterglow, excellent stretchability, self-healable and recyclable properties. Impressively, the polymers can be stretched up to 500% without significant loss in RTP intensity and lifetime, and they possess a self-healing ability with a healing efficiency of 69.6%. Utilizing these photoactivated and stretchable persistent RTP polymers, dual encryption can be achieved under UV irradiation and stretching conditions, thereby enhancing the security levels of the stored confidential information. Overall, this study represents the first example of self-healable and recyclable stimuli-responsive RTP materials, demonstrating their bright future for the flexible and wearable optoelectronics.

本征可拉伸、自愈合和可回收聚合物中的光激活多色有机磷光体
能够对微环境变化做出响应的智能持久性有机室温磷光(RTP)材料在各种光电应用中至关重要。然而,传统的持久性 RTP 材料通常不具备伸展性和柔韧性,从而限制了一些实际应用。本研究报告了一种简便的单锅光引发共聚方法,用于制备具有多色余辉、优异的拉伸性、自愈合性和可回收性的光激活持久性 RTP 聚合物。令人印象深刻的是,这些聚合物可拉伸高达 500%,而 RTP 强度和寿命不会有明显损失,而且它们还具有自愈能力,愈合效率高达 69.6%。利用这些光激活和可拉伸的持久性 RTP 聚合物,可以在紫外线照射和拉伸条件下实现双重加密,从而提高所存储机密信息的安全级别。总之,这项研究代表了自愈合和可回收刺激响应型 RTP 材料的首个范例,展示了其在柔性和可穿戴光电子领域的广阔前景。
