Problems solved by technology

Because of this, in the design and synthesis of organic nonlinear optical materials, a large number of experimental operations are required to prove that the designed molecules have better photoelectric properties, which is especially high in human resource costs, and for the device fabrication of the materials themselves, It also requires special process and equipment support, so it is difficult to solve its difficulties

At present, the photochemical stability of organic nonlinear optical materials with "D-A-π-A" structure is not good, and they are easy to photobleach during use, which makes the device life short and cannot be used for a long time
