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.
塑料是用途广泛的材料，在各个行业都能提供轻质、耐用且经济实惠的解决方案。然而，其不可降解的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提取方法，利用废弃的聚（双酚A碳酸酯）（PC）作为反应前体，合成活性呋喃作为光开关斯滕豪斯加合物的前体。这种创新的化学策略不仅生成了N，N'-官能化巴比妥酸盐，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，还产生了可重复使用的双酚A（BPA）。此外，衍生的活性呋喃通过在胺化聚合物表面形成有色供体-受体斯滕豪斯加合物（DASA）来展现其功能。这项工作展示了从线性塑料经济向循环塑料经济的转变，突出了塑料废物作为创造性能改进材料资源的潜力。
