【菁类低维度光电导聚合物功能材料的研究】.pdf
摘 要 本论文首先进行了分子结构一维的光电导功能高分子的分子设 计。首次采用具有有利于光电导性的-NH-官能团的乙二胺和4,4”-二氨基二苯醚(DADP)作为桥配体和C12SiPe单体反应,通过溶剂、温度、原料配比、反应时间等条件的选择,成功地合成出分子结构 一维的乙二胺桥键酞菁硅聚合物(I)和4,4 -二氨基二苯醚桥键酞 菁硅聚合物(II),并应用IR、UV/Vis、元素分析等手段对其结构进 行了表征.首次采用电场取向法制备了酞菁类低维度光电导功能材料,着 重通过偏振荧光、FTIR反射吸收、角分辩XPS、DSC以及TEM五种手 段对其低维有序性进行了表征。
