Abstract

The invention relates to the field of optical properties and particularly relates to a preparation method of a U-shaped asymmetric non-linear optical inorganic-organic hybrid material. The preparation method comprises the following steps: adding 0.7mmol-1.3mmol of CaCl2, 0.7mmol-1.3mmol of isophthalic acid-5-sodium sulfonate, 1.8mmol-2.2mmol of 1,10-phenanthroline, 0.08mL-0.12mL of 1M NaOH and 13mL-15mL of de-ionized water into a reaction kettle; heating at 155 DEG C-165 DEG C for 4d-7d; and then cooling and filtering to obtain a block-shaped colorless crystal. Compared with the prior art, the preparation method of the U-shaped asymmetric non-linear optical inorganic-organic hybrid material has the advantages that a material with a non-linear optical property is expanded into the inorganic-organic hybrid material; the inorganic-organic hybrid material is synthesized by utilizing a ligand with a symmetrical structure and calcium metal ions; and an asymmetric compound is formed by utilizing the symmetrical ligand, and has non-linear optical property.

Description

technical field [0001] The invention relates to the field of optical properties, in particular to a method for preparing a U-shaped asymmetric nonlinear optical inorganic-organic hybrid material. Background technique [0002] The existing second-order nonlinear optical materials are mostly concentrated in lithium iodate, lithium niobate, etc., and semiconductor crystals, such as tellurium and red silver ore (Ag 3 AsS 3 ) and other inorganic compounds. [0003] For example, Chinese patent application CN 105568380 A "A Novel Infrared Nonlinear Optical Material and Its Preparation Method and Application" discloses a novel infrared nonlinear optical material with the molecular formula RbHgI 3 , the outstanding feature of this material is that it has a large second-order nonlinear optical coefficient that can be phase-matched, has a wide light transmission window in the ultraviolet, visible and infrared regions, and has good thermal stability. The synthesis method is to RbI an...
