In this study, four new silicon-containing poly(ether-azomethine)s with linear structures were prepared using original silicon and biphenyl moiety-containing monomers: two diamines and two dialdehydes. The oligomeric natures of the samples were established by GPC analysis, which showed chains containing 3 to 5 repetitive units. The monomers and the oligomeric samples were structurally characterized by NMR and FT-IR spectroscopy. The solubilities of the samples in common organic solvents and their thermal behavior enable improvement of their industrial and technological processability. The optical band gaps of the oligomeric samples were estimated from optical measurements (UV-vis), and their electrical behavior in films was determined using the four-point method. The surface arrangements and morphological characteristics of the films were determined atomic force microscopy measurements. The roughness, area increase percentage and layer stiffness of the films were also measured using this technique.
在本研究中，使用含原始硅和联苯部分的单体（两种二胺和两种二醛）制备了四种具有线性结构的新型含硅聚（醚 - 偶氮甲碱）。通过凝胶渗透色谱（GPC）分析确定了样品的低聚性质，结果表明链中含有3至5个重复单元。通过核磁共振（NMR）和傅里叶变换红外光谱（FT - IR）对单体和低聚样品进行了结构表征。样品在常见有机溶剂中的溶解性及其热行为有助于改善其工业和工艺加工性能。通过光学测量（紫外 - 可见光谱）估算了低聚样品的光学带隙，并使用四点法测定了其在薄膜中的电学行为。通过原子力显微镜测量确定了薄膜的表面排列和形态特征。还使用该技术测量了薄膜的粗糙度、面积增加百分比和层刚度。
