Preparation method of polymetal carbosilane precursor
The invention discloses a preparation method of a polymetal carbosilane precursor, which comprises the following steps: sequentially adding alkali metal and metallocene into an organic solvent in a protective atmosphere, then dropwise adding chlorosilane, carrying out first reaction, solid-liquid separation and solvent removal to obtain a reactant B, and then carrying out second reaction on the reactant B and a reactant A in the protective atmosphere to obtain the polymetal carbosilane precursor. And removing the solvent to obtain polymetal carbosilane, wherein the reactant A is liquid polysilicon carbosilane. According to the preparation method, a large amount of metal is introduced through the reaction of chlorosilane and metallocene, a reactant B which has high reaction activity and contains more Si-Si bonds is obtained at the same time, then the reactant B continues to react with liquid polysilicocarbosilane, and the obtained product has high metal content and good performance stability at the same time. And the distribution of metal elements is uniform, the metal content is adjustable, and the precursor does not contain oxygen.
本发明公开了一种聚金属碳硅烷先驱体的制备方法，包括以下步骤：在保护气氛下将碱金属、茂金属依次加入有机溶剂中，然后再滴入氯硅烷，第一次反应、固液分离，脱除溶剂获得反应物B，然后于保护气氛下将反应物B与反应物A进行第二次反应，脱除溶剂即得聚金属碳硅烷，所述反应物A为液态聚硅碳硅烷。本发明的制备方法，先通过氯硅烷与茂金属反应引入大量的金属，同时获得具有高的反应活性的，含较多Si‑Si键的反应物B，然后再将反应物B继续与液态聚硅碳硅烷反应，得到的产物含有较高金属含量的且同时具有较好的性能稳定性，且金属元素的分布均匀，金属含量可调，且先驱体中不含氧。
