Paragraph 0044; 0047, (2021/07/10)
The invention discloses a chiral ONO tridentate Schiff base carboxylic acid ligand and relates to the technical field of coordination compounds, wherein the structural formula of the chiral ONO tridentate Schiff base carboxylic acid ligand is shown in the specification. The invention also provides a preparation method of the ligand and a complex based on the ligand. The chiral ONO tridentate Schiff base carboxylic acid ligand has the beneficial effects that the chiral ONO tridentate Schiff base carboxylic acid ligand prepared by the method can be prepared by simple reaction of cheap raw materials and abundant chiral sources, the preparation cost and the synthesis difficulty of the chiral ligand are reduced favourably, and the chiral ONO tridentate Schiff base carboxylic acid ligand contains a unique ONO chelating coordination mode, and the preparation of the Schiff base chiral complex with a rich structure is facilitated.
