Although multidentate heteroatomic could catalyse high selectivity of α-olefin such as 1-hexene and 1-octene,these ligand usually use expensive co-catalyst such as MAO,so it hardly has broad application in α-olefin field.

但由于多齿杂原子配体一般需由价格相对昂贵的烷基铝氧烷，特别是MAO的活化才可进行高效催化反应，因此长期以来多齿型配体难以得到广泛应用。

Synthesizing new compounds are always the goal of chemist. Recent ly, the progress of the hydrothermal synthesis method is giving a new method to synthesize new compounds. The hydrothermal synthesis method is prefectly applied to synthesizing the tunnling materials, micro-and meso-porous mat erials as well as some new materials, so this method obtained the intrest of che mist.
