首次将2，3，5，6-Tetrakis-(morpholinomethyl)hydroquinone(1)用于水-甲醇介质中HAuCl4还原法制备金纳米粒子。化合物1由对苯二酚和吗啉通过Mannich-型氨甲基化反应得到。用元素分析、FT-IR、UV-Vis和MS对其进行了表征，最后用单晶X射线衍射法对其进行了表征。HAuCl4和化合物1的比例对控制金纳米粒子的形状和尺寸起着至关重要的作用。用透射电子显微镜、X射线衍射仪、傅立叶变换红外光谱、紫外-可见光谱对样品进行了表征。随着金(III)溶液相对化合物1含量的增加，观察到了两种不同的形貌，如自组装的金纳米颗粒和球形的金纳米颗粒。结果表明，通过改变化合物1和金(III)溶液的浓度可以控制不同尺寸的金纳米粒子的形貌。
2,3,5,6-Tetrakis-(morpholinomethyl)hydroquinone (1) is used for the first time in the preparation of gold nanoparticles by the reduction of HAuCl4in water–methanol medium without using any capping agent. Compound 1 was prepared by Mannich-type aminomethylation of hydroquinone with morpholine. It is characterized by elemental analysis, FT-IR, UV–Vis and mass spectra and finally by single crystal X-ray diffraction. The ratio of HAuCl4and compound 1 played a vital role in controlling the shape and size of gold nanoparticles. The samples were characterized by Transmission Electron Microscopy (TEM), XRD, FT-IR, UV–Vis measurements. With the increasing amount of gold(III) solution with respect to compound 1, two different morphologies such as self-assembled and spherical gold nanoparticles have been observed. The results indicate that the morphology of gold nanoparticles with different sizes can be controlled by changing the concentrations of compound 1 and gold(III) solution.
