A kind of one-dimensional chiral cu(ii) chain complex and its preparation method and application

Abstract

The invention discloses a one-dimensional chiral Cu (II) chain complex and a preparation method thereof. The preparation method comprises firstly synthesizing a chiral organic ligand L, then synthesizing a chiral Cu (II) molecular building unit through coordination, finally dissolving the chiral Cu (II) molecular building unit and 2, 6-pyridinedicarboxylic acid in methanol for a reaction, and after the reaction, cooling the product to the room temperature to obtain the red one-dimensional chiral Cu (II) chain complex. The one-dimensional chiral Cu (II) chain complex is obtained by coordination reaction of chiral ligands, enriches the family of chiral metal complexes and lays the foundation for further study and use. The preparation method is carried out at a mild reaction temperature, has simple reaction processes and a high yield and easily realizes industrial larhe-scale production. The one-dimensional chiral Cu (II) chain complex is useful as a molecular material in the field of chiral application.

Description

technical field [0001] The invention belongs to the technical field of asymmetric synthesis, and in particular relates to a one-dimensional chiral Cu(II) chain complex and its preparation method and application. Background technique [0002] Chirality is a fundamental feature of nature. Chiral molecules are closely related to human physiology and life. Specific chiral molecules have certain special optical or electronic properties and are key substances for high-tech products. The substances existing in nature come from animals and plants, which shows its limitations and limitations. Therefore, how to synthesize chiral molecules more economically and selectively to meet people's growing needs is asymmetric synthesis. focus and difficulty. [0003] After decades of research, it has been found that chiral metal complexes produced during the equilibrium process between metal ions and chiral ligands are attractive because of their diverse structures and excellent properties in...

Problems solved by technology

However, the synthesis of such compounds is relatively difficult. Generally, chiral complexes can be obtained through the induction of chiral templates, but the chiral complexes obtained by this method are more accidental. Another method is directly through chiral ligands. To directly synthesize chiral complexes, this method has a higher probability of obtaining chiral complexes, so generally chiral complexes are obtained directly by chiral ligand coordination

But up to now, there are still few chiral metal complexes synthesized by people, which cannot meet the needs of scientific research and actual production.
