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.

本质可拉伸、自修复和可回收聚合物中的光活化多色有机磷光


能够响应微环境变化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 材料通常不具有可拉伸性和柔韧性，从而限制了一些实际应用。本研究报告了一种简单的单锅法光引发共聚，用于制备具有多色余辉、优异拉伸性、自修复和可回收特性的光活化持久性 RTP 聚合物。令人印象深刻的是，聚合物可以拉伸高达 500%，而不会显着损失 RTP 强度和使用寿命，并且它们具有 69.6% 的自修复能力。利用这些光活化和可拉伸的持久性 RTP 聚合物，可以在紫外线照射和拉伸条件下实现双重加密，从而提高存储机密信息的安全级别。总体而言，这项研究代表了可自修复和可回收刺激响应 RTP 材料的第一个例子，展示了它们在柔性和可穿戴光电子学中的光明前景。
