Abstract

The invention relates to the field of second-order nonlinear optics and concretely relates to a method for preparing a coordination polymer having a frequency-doubled effect. The method comprises dissolving a metal salt and 5-sulfoisophthalic acid monosodium salt in water according to ratio of the metal salt, 5-sulfoisophthalic acid monosodium salt to water of 0.5 to 2mmol: 0.5 to 2mmol: 10 to 30mL, carrying out mixing, putting the mixed liquid into a reactor, heating the mixed liquid at a temperature of 120 to 150 DEG C for 2 to 5 days, and carrying out cooling and filtration to obtain bulk crystals. The kind of the materials with the frequency-doubled effect is expanded to the field of metal organic framework compounds. The produced compound has the frequency-doubled effect, fluorescence properties and magnetic properties. The synthesis method is simple and is easy to control and has a high yield.

Description

technical field [0001] The invention relates to the field of second-order nonlinear optics, in particular to a preparation method of a coordination polymer with frequency doubling effect. 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 ), etc. These materials have good thermal stability and do not decompose at higher temperatures. [0003] At the same time, the existing methods for synthesizing metal-organic framework compounds with frequency-doubling effect are not very widely used, and only a metal-organic framework compound with frequency-doubling effect is synthesized. [0004] 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 ...
