Embodiment

[0016] The preparation process steps of 4-(4-hydroxyl 3,5-dimethylstyryl)picoline p-aminobenzenesulfonate described in this embodiment are:

[0017] (1) Measure 4-methylpyridinium iodide salt and 4-hydroxy-3,5-dimethylbenzaldehyde according to the molar ratio of 1~1, dissolve them in 40~60ml of methanol, then pour them into a three-hole flask, at 70°C Under the condition of magnetic stirring, then 3ml of piperidine was added dropwise as a catalyst, condensed and refluxed for 24 hours to obtain a dark yellow solid, which was dried to obtain 4-(4-hydroxyl 3,5-dimethylstyryl)picoline iodide;

[0018] (2) Weigh 4-(4-hydroxyl 3,5-dimethylstyryl) picoline iodide and sodium p-aminobenzenesulfonic acid with a molar ratio of 1:1, and then dissolve them in 500ml of distilled water , adjust the temperature to 80°C, stir the reaction for 2h, until a yellow precipitate is formed at the bottom of the flask;

[0019] (3) Cool the solution and the yellow precipitate after the reaction in ste...

Abstract

The invention belongs to the technical field of functional materials and preparation thereof, and relates to 4-(4-hydroxy-3, 5-dimethylstyryl) methylpyridine p-aminobenzene sulfonic acid salt and a preparation method thereof. The preparation method comprises the following steps: firstly, mixing 4-methylpyridine iodized salt with 4 hydroxyl-3, 5-dimethylbenzaldehyde, putting into methanol, pouring into a flask, carrying out an ion exchange reaction and a condensation reflux reaction to obtain 4-(4 hydroxyl-3, 5-dimethylstyryl) methylpyridine iodide, purifying, dissolving in water, heating and stirring, then adding sodium sulfanilate, heating to react until a yellow solid is generated, drying to obtain a 4-(4 hydroxyl-3, 5-dimethylstyryl) methylpyridine p-aminobenzene sulfonic acid salt crystal growth raw material, and finally recrystallizing the obtained growth raw material by using methanol and filtering to obtain high-purity 4-(4-hydroxyl-3, 5-dimethylstyryl) methylpyridine p-aminobenzene sulfonic acid salt. The preparation method is simple and convenient, the cost is low, the environment is not easily polluted when the crystal raw material is synthesized in water, the yield is high, and the product has a high second-order nonlinear coefficient.

Description

Technical field: [0001] The invention belongs to the technical field of functional materials and their preparation, and relates to an organic nonlinear crystal raw material and a preparation method thereof, in particular to a 4-(4-hydroxyl 3,5-dimethylstyryl)picoline p-aminobenzenesulfonate Acid acid salt and its preparation method. Background technique: [0002] Due to the wide application of nonlinear optics (NLO) in the fields of optical computing and optical communication, finding new materials with nonlinear optics (NLO) properties has always been a research hotspot. Compared with the currently studied inorganic materials, organic nonlinear optical materials with large second-order nonlinear optical properties have always been a hot spot of attention. This is partly because their molecular structure and properties can be easily tuned for various applications. On the other hand, compared with inorganic materials, organic materials have broad application prospects in se...
