Embodiment Construction

[0056] The present invention is further described in conjunction with the following examples.

[0057] The embodiment of the present invention relates to four kinds of organic optical nonlinear chromophores BLD1-4 based on the double-donor structure, and its structure is shown in the attached Figure 2-5 , the chromophore BLD1-4 shows good solubility in common organic solvents, such as ethyl acetate, ethanol and acetone etc., its synthetic method comprises the following steps:

[0058] S1. Add 4,4-difluorobenzophenone (compound (1)) (10.0 g, 46.8 mol) and 2-(ethylamino) ethanol (20.4 g, 229 mmol) to a 500 mL circle equipped with a reflux condenser Bottom flask, and reacted at 180°C under a nitrogen atmosphere for 2d. After the reaction was completed, the mixture was cooled, and the aqueous layer was extracted with ethyl acetate and water, and then the water was removed. Using ethyl acetate / ethanol as a developing solvent, the column chromatography Purify, and then remove resi...

Abstract

The invention provides an organic optical non-linear chromophore based on a double-donor structure, and belongs to the field of optical materials, the chromophore has a structural formula shown in the abstract figure, OH groups are introduced into double donors of a second-order non-linear optical chromophore through nucleophilic reaction, and the chromophore has a structure shown in the description. The two OH groups connected to the donor end provide connection sites for further modification of the double donor, and ultraviolet absorption lambda max red shift and small band gap verify that the double donor group modified by the two OH groups has higher electron donor strength compared with the donors of most chromophores.

Description

technical field [0001] The invention relates to the field of organic optical materials, in particular to an organic optical nonlinear chromophore based on a double-donor structure and its synthesis method and application. Background technique [0002] Driven by next-generation information technologies such as 5G, the Internet of Things, virtual reality, and artificial intelligence, broadband waves are sweeping the world. In the past decade, the information capacity has increased exponentially, and the bandwidth and energy consumption of optical communication networks are under great pressure. The electro-optic modulator is the core device to realize photoelectric information conversion, and it is also the key link to break through the two major technical challenges of bandwidth and energy consumption. [0003] Electro-optic materials are the building blocks of electro-optic modulators. Early research on nonlinear optical materials mainly focused on inorganic crystals and s...
