采用Claisen-Schmidt缩合反应法合成了查耳酮衍生物1-(4-甲氧基苯基)-3-(3,4-二甲氧基苯基)-2-丙烯-1-酮(DMMC)。 DMMC 在甲醇中的生长采用缓慢蒸发技术。单晶X射线衍射表明DMMC的空间群为P21。通过赫什菲尔德面分析晶体的分子间相互作用。采用Kurtz-Perry粉末法测定了DMMC的二次谐波产生效率。当粒径在250~300μm之间时，DMMC的倍频效率最大，约为同粒径KDP的60倍。通过FT-IR和1H NMR谱鉴定了晶体的所有官能团。该晶体在 350−2000 nm 范围内具有较宽的传输范围，截止波长为 400 nm。测试样品的热性能，熔点为95.59℃。发现该化合物的介电常数在 45 °C 以下为 17。
1-(4-methoxyphenyl)-3-(3,4-dimethoxyphenyl)-2-propen-1-one(DMMC), a chalcone derivative was synthesized by Claisen-Schmidt condensation reaction method. The growth of DMMC in methanol was used the slow evaporation technique. Single crystal X-ray diffraction revealed that the space group of DMMC is P21. The intermolecular interaction of crystal was analyzed by Hirshfeld surface. The second harmonic generation efficiency of DMMC was measured by Kurtz-Perry powder method. When the particle size was between 250 and 300 μm, the SHG efficiency of DMMC was the largest, which was about 60 times that of the KDP with the same particle size. All functional groups of the crystal were identified by FT-IR and1H NMR spectral. This crystal had a wide transmission range in the region of 350−2000 nm with the cut off wavelength is 400 nm. The thermal properties of the sample were tested, and the melting point was at 95.59 °C. The dielectric constant of the compounds was found to be 17 below 45 °C.
