different arylamine moieties. Using slow evaporation, the four fluorenone derivatives (FO1-4) exhibit good ability to arrange into microstructures in the solid state. The electronic and steric effects of arylamine substituents influence both optical features and aggregation processes, as evidenced by photophysical and XRD characterization. SEM investigations have shown that the four FO1-4 derivatives arrange
在这项工作中,芴酮分子在3,6-位被四个不同的芳胺部分对称地双官能化。使用缓慢蒸发,四种芴酮衍生物(FO1-4)表现出良好的排列成固态微结构的能力。光物理和XRD表征证明,芳基胺取代基的电子和空间效应会影响光学特征和聚集过程。SEM研究表明,四种FO1-4衍生物排列在四个不同的微观结构中。更具体地说,FO1的自组装一维微带状结构表现出出色的光损耗系数(α),低至0.006dBμm -1,暗示了这些材料在光波导领域的潜在用途。
