The synthetic method of the azo compound is simple, convenient, controllable and high in yield, and the product has an excellent non-linear optical property and potential application prospects in fields such as optical devices, anti-fatigue devices and optical limiting devices.

Description

technical field [0001] The invention relates to a class of azo compounds, in particular to a novel azo compound with nonlinear optical properties and a synthesis method thereof. The invention belongs to the field of optical smart material technology and related devices. Background technique [0002] Since the development of nonlinear optical materials, many nonlinear optical materials such as organic, inorganic, polymer, and organometallic have emerged as the times require. Among them, organic materials, as the leading force, have developed rapidly in the nonlinear field. Compared with other nonlinear materials, organic materials have the advantages of strong controllability, easy structure regulation, strong activatability, and strong compatibility with other macromolecules. Therefore, organic nonlinear materials are widely used as nonlinear dominant materials. various fields. Among them, azo compounds, as a branch of organic nonlinear materials, have also received extens...
