光纤技术已经彻底改变了电信行业，但在化学领域仍未得到充分利用。作为光反应器的一部分，光纤为在化学反应中引入和容纳光开辟了许多途径。这项工作首次展示了一种将光催化纳米多孔框架（Co ZIF-67）整合到光纤内部毛细管中的设计策略，从而创建了一个一体化、即插即用的光反应器。相对于粉末形式，该系统提高了光催化剂的反应活性，用于 C-H 活化，导致 C-C 键形成，这是制药和有机合成中的一个重要过程。使用太阳能和低温进行该反应表明这些系统在大规模工业应用中具有明显的潜力。
Optical fiber technology has revolutionized the telecommunications industry, though is still under‐utilized in chemistry. Optical fibers open many avenues for introducing, and containing, light in chemical reactions, as part of a photoreactor. This work shows, for the first time, a design strategy for incorporating a photocatalytic, nanoporous framework (Co ZIF‐67) within the internal capillaries of an optical fiber, in doing so creating an all‐in‐one, plug‐in‐and‐play photoreactor. This system improves the reactivity of the photocatalyst, relative to the powdered form, for CH activation leading to CC bond formation, a significant process in pharmaceutical and organic synthesis. Performing this reaction using solar energy, and low temperature demonstrates the clear potential for these systems for large scale industrial applications.
