Embodiment 1
[0078] An organic optical nonlinear chromophore based on a single-donor self-assembled structure, including H1-H3, its structure is shown in the appendix Figure 4 , the chromophore H4 shows good solubility in common organic solvents, such as ethyl acetate, ethanol and acetone.
[0079] Its preparation process includes the synthesis of chromophore H4, and the steps are as follows:
[0080] P1. Under argon atmosphere, under ice bath condition, add metallic sodium (88.23mmol, 2.0g) to the two-necked flask, dissolve with an appropriate amount of ethanol, add 2-mercaptoethanol (88.23mmol, 6.89g, 7.65mL), After 20 mins, compound 1 (132.35 mmol, 20.68 g) was added. After 1 h, compound 2b (88.23 mmol, 23.23 g) dissolved in an appropriate amount of ethanol was added. The reaction was refluxed overnight at 65°C. Chromatography column, the eluent ratio is 1:8-1:3 (EA:PE), to obtain compound 3b (30.30 g, 65.9 mmol), yield: 74.7%, red oily liquid;
