Just in the past few years, the application of 4CzIPN as a photocatalyst in photochemistry has been dramatically increased with its unique properties. In the literature, a variety of protocols for the synthesis of 4CzIPN have been reported. However, a practical process for the preparation of 4CzIPN with consistent quality on large scale is not available, but highly desirable to enable the robust application of this photocatalysis in industry. Herein, we detailed a practical and simple column-free chemical process amenable for the large-scale production of 4CzIPN with high quality in 91% yield. Current process was demonstrated on large scale. The similar process protocol was applicable and demonstrated for the synthesis of 3DPA2FBN on large scale.

就在过去的几年里，4CzIPN作为光催化剂以其独特的性能在光化学中的应用急剧增加。文献中报道了多种 4CzIPN 的合成方案。然而，大规模制备质量稳定的 4CzIPN 的实用方法尚不存在，但非常需要使这种光催化在工业中得到稳健应用。在此，我们详细介绍了一种实用且简单的无柱化学工艺，适合大规模生产高质量的 4CzIPN，收率达 91%。目前的工艺已被大规模演示。类似的工艺方案适用于大规模合成 3DPA2FBN，并已得到证实。
