Metal nitride clusterfullerenes (NCFs) have significant applications in molecular electronics, biomedical imaging, and nonlinear optical devices due to their unique structures. However, their wide applications are limited by the production quantity. In this work, the yields of metal nitride clusterfullerenes M₃N@C₈₀ (M=Y, Sc, Gd) were greatly enhanced by utilizing zirconium nitride (ZrN) as an efficient nitrogen source for the arc-discharge method. Compared with the traditional synthetic route using N₂ gas as nitrogen source, the ZrN inside graphite tube can be vaporized simultaneously with metal and graphite, and then afford the high concentration of nitrogen atoms in the arc region, which will promote the formation of metal nitride clusterfullerenes finally. The ZrN can promote the yields of Y₃N@C₈₀, Sc₃N@C₈₀ and Gd₃N@C₈₀, revealing the universal applicability of ZrN as a highly efficient nitrogen source. Specifically, the yield of Sc₃N@C₈₀ was greatly improved when adding ZrN, and it shows over double yield compared to traditional synthetic route using N₂ gas. In addition, ZrN can also enhance the yields of paramagnetic azametallofullerene M₂@C₇₉N due to the high concentration of nitrogen atoms in the arc region. This new method enhances the production quantity of metal nitride clusterfullerenes and azametallofullerenes, and it will greatly promote the research and application of these molecular carbon materials.

金属氮化物簇富勒烯（NCF）由于其独特的结构在分子电子学，生物医学成像和非线性光学器件中具有重要的应用。但是，它们的广泛应用受到产量的限制。在这项工作中，通过利用氮化锆（ZrN）作为电弧放电方法的有效氮源，大大提高了金属氮化物簇富勒烯M ₃ N @ C ₈₀（M = Y，Sc，Gd）的产率。与使用N ₂的传统合成路线相比气体作为氮源，石墨管内的ZrN可以与金属和石墨同时汽化，然后在电弧区提供高浓度的氮原子，这最终将促进金属氮化物团簇富勒烯的形成。ZrN可以提高Y ₃ N @ C ₈₀，Sc ₃ N @ C ₈₀和Gd ₃ N @ C _80的产率，显示出ZrN作为高效氮源的普遍适用性。具体而言，添加ZrN可以大大提高Sc ₃ N @ C _80的收率，与使用N _2的传统合成路线相比，它的收率高出一倍。加油站。另外，由于电弧区域​​中氮原子的高浓度，ZrN还可以提高顺磁性氮杂金属富勒烯M ₂ @C ₇₉ N的产率。该新方法提高了金属氮化物簇富勒烯和氮杂金属富勒烯的生产量，将大大促进这些分子碳材料的研究和应用。
