Abstract

The invention relates to the field of second order nonlinear optics, and more specifically relates to a preparation method of a metal organic framework compound with nonlinear optical properties. The method comprises the following steps: 0.5-2mmol of SrCl2 and 0.5-2mmol of 5-sulfoisophthalic acid monosodium salt are dissolved in 10-17ml of water, the materials are placed in a reaction vessel at 140-170 DEG C and heating is carried out for 2-4 days, cooling and filtering are carried out, in order to obtain bulk crystals. Preferable steps are as follows: 1mmol of SrCl2 and 1mmol of 5-sulfoisophthalic acid monosodium salt are dissolved in 15ml of water, the materials are placed in a reaction vessel at 160 DEG C and heating is carried out for 3 days, cooling and filtering are carried out, in order to obtain bulk crystals. Compared with the prior art, the material with nonlinear optical properties is expanded to the inorganic-organic hybrid material, and the synthetic material has nonlinear optical and fluorescent properties, and has the advantages of various structures, designable and regulatable properties, and the like.

Description

technical field [0001] The invention relates to the field of second-order nonlinear optics, in particular to a method for preparing a metal-organic framework compound with nonlinear optical properties. Background technique [0002] The existing second-order nonlinear optical materials are mostly concentrated in lithium iodate, lithium niobate, and semiconductor crystals, such as tellurium and red silver ore (Ag 3 AsS 3 ) and other inorganic compounds, these materials have good thermal stability and do not decompose at higher temperatures. [0003] 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...
