The invention discloses a bis-SalenAl complex as well as a preparation method and application thereof, and belongs to the technical field of synthesis and catalytic application of fine chemicals and complexes. The preparation method comprises the following steps: adding an auxiliary ligand L2 of another molecule Salen skeleton into a solution of a SalenAl complex, or simultaneously adding ligands L1 and L2 of the Salen skeleton, AlR3 and a solvent into a reactor, and reacting to obtain the double-SalenAl complex. The complex obtained by the invention has the characteristics of low price, low toxicity, no heavy metal and harmful substances, small environmental pollution and the like. The preparation process of the complex has the advantages of mild conditions, simple operation, convenient post-treatment and the like, and is a catalyst system with a good application prospect. 本发明公开了一种双SalenAl配合物及其制备方法和应用，属于精细化学品和配合物合成及催化应用技术领域。本发明通过在SalenAl配合物的溶液中添加另一分子Salen骨架的辅助配体L2，或在反应器中同时添加Salen骨架的配体L1和L2、AlR3、溶剂反应制得双SalenA
