Photoswitchable fluorescent polymers (PFPs) are emerging as a class of promising systems for photowritable pattern, optical anti-counterfeiting, and information encryption. They typically use harmful UV light as the stimulus, which often leads to inevitable photobleaching and poor reversibility. To address this issue, visible-light-driven PFPs by copolymerization of novel negative photochromic spiropyran monomer and methyl acrylate are developed. The obtained copolymers display bright red fluorescence, which can be reversibly turned off by visible light irradiation. Many appealing features are observed in this system, including fast photo-responsibility, prominent photo-reversibility and photostability, simple preparation process, and processability. Their applications in photorewritable patterns, optical anti-counterfeiting, and information encryption are also demonstrated.

用于光可重写图案、防伪和信息加密的可见光驱动光可切换荧光聚合物

光开关荧光聚合物（PFP）正在成为一类用于光写图案、光学防伪和信息加密的有前途的系统。他们通常使用有害的紫外线作为刺激，这通常会导致不可避免的光漂白和可逆性差。为了解决这个问题，通过新型负性光致变色螺吡喃单体和丙烯酸甲酯的共聚开发了可见光驱动的 PFP。所得共聚物显示出明亮的红色荧光，该荧光可以通过可见光照射可逆地关闭。该系统具有许多吸引人的特点，包括快速的光响应性、突出的光可逆性和光稳定性、简单的制备过程和可加工性。还展示了它们在光可重写图案、光学防伪和信息加密方面的应用。
