Problems solved by technology

[0004] When organic molecules or their complexes form crystals, due to the electrostatic interaction between molecules, a centrally symmetrical crystal space group may be generated, resulting in the loss of nonlinear effects of the crystal.
However, it is difficult to control its structure during crystal growth.

Abstract

The invention relates to a glutamic acid-derived chiral metal-organic nonlinear optical material. The invention discloses a metal-complex nonlinear optical crystal material containing a chiral center. The chemical formula of the material is [ML(H2O)]n, wherein M=Mn or Cd; and L is a chiral ligand. A preparation method of the material comprises the step of complexing an L-glutamic acid derivative as a ligand with metals, such as cadmium or manganese and the like in an aqueous solution to form the material. The material has the characteristic that the existence of a non-central space group necessary for a second-order nonlinear optical crystal material is ensured through a chiral group. The material has simple preparation method, and the prepared compound crystal has stable performance and better second-order nonlinear optical property and is expected to be widely applied to the field of developing a short-wave laser, a light modulator and the like.
