| 摘 要： | 采用再沉淀法,以CTAB为稳定剂和软模板,制备了有机小分子9,10-二苯基蒽(DPA)的纳米粒子.考察了CTAB的浓度对生成的DPA纳米粒子的尺寸和形貌的影响.结果表明,加入CTAB有利于制备形貌规则和尺寸均匀的DPA纳米粒子.CTAB浓度较高条件下制备的DPA粒子为带状形貌,带宽约为300 nm左右,片长约为6μm,厚度约为几十纳米.

| Abstract: | Organic nanoparticles based on small molecule 9, 10-diphenylanthracene (DPA) were prepared by reprecipitation method in the presence of cetyltrimethylammonium bromide (CTAB) as a stabilizer and template. The effects of the concentration of CTAB on the size and morphology of the prepared DPA nanoparticles were investigated. The results reveal that the adding of CTAB contributes to the formation of regular and uniform DPA nanoparticles. The DPA nanoparticles prepared with high concentration of CTAB have regular ribbon-like shape, with the width of about 300 nm, the length of 6 ?m and the thickness of a few tens of nanometers. |
