Plastics are versatile materials, offering lightweight, durable, and affordable solutions across various industries. However, their non‐degradable nature poses challenges by end of their life. This study presented an innovative carbonyl extraction method to utilize waste poly(bisphenol A carbonate) (PC) as reaction precursor to synthesis of activated furan as precursor for photoswitchable Stenhouse adducts. This innovative chemical strategy not only generated N,N’‐functionalized barbiturates but also provided an eco‐friendly and cost‐effective alternative to traditional synthesis methods. The method presented hereby not only promotes sustainability by repurposing waste polycarbonate as carbonyl equivalent under green conditions but also yielded reusable bisphenol A (BPA). Furthermore, the derived activated furans exhibited their functionality by forming colored donor‐acceptor Stenhouse adducts (DASAs) on aminated polymer surfaces. This work demonstrated a transition from a linear plastics economy toward a circular one, highlighting the potential of plastic waste as a resource for creating materials with improved properties.

可持续利用废弃聚碳酸酯合成活性呋喃，在聚合物表面生成斯滕豪斯加合物

塑料是一种多功能材料，可为各个行业提供轻质、耐用且经济实惠的解决方案。然而，它们的不可降解特性在其使用寿命结束时带来了挑战。本研究提出了一种创新的羰基萃取方法，利用废弃的聚（双酚 A 碳酸酯）（PC）作为反应前体来合成活性呋喃，作为光开关 Stenhouse 加合物的前体。这种创新的化学策略不仅产生了 N,N' 功能化巴比妥酸盐，而且还为传统合成方法提供了一种环保且经济高效的替代方案。本文提出的方法不仅通过在绿色条件下将废弃聚碳酸酯重新用作羰基等价物来促进可持续性，而且还产生了可重复使用的双酚A（BPA）。此外，衍生的活化呋喃通过在胺化聚合物表面形成有色的供体-受体斯滕豪斯加合物（DASA）来展示其功能。这项工作展示了从线性塑料经济向循环经济的转变，凸显了塑料废物作为创造具有改进性能的材料的资源的潜力。
