A D–π–A type triphenylamine derivative 3-(4-(diphenylamino)phenyl)acrylic acid (abbreviated as L) is designed, synthesized and characterized by single crystal X-ray diffraction analysis. The self-aggregation of L nanostructures in different acidity aqueous solutions and/or under the guidance of rare earth (RE) ions is studied, along with the corresponding optical properties. In strong acidic conditions
通过单晶X射线衍射分析设计,合成并表征了AD-π-A型三苯胺衍生物3-(4-(二苯氨基)苯基)丙烯酸(简称L)。研究了L纳米结构在不同酸度水溶液中和/或在稀土(RE)离子的引导下的自聚集,以及相应的光学性质。在强酸性条件下,L分子自组装形成二维纳米结构。在中性水溶液中,L倾向于形成纳米棒。在强碱环境下,获得了纳米纤维。此外,在酸性条件下,Tm 3+的存在会诱导L分子自聚集成纳米板。当使用Yb 3+时,观察到花状六个分支结构。改变的形态导致可调的线性光学性质。
