可溶性聚吡咯甲烷的制备与光学性能研究

摘要

Two soluble poly( pyrrolyl methane) derivatives( Polymer A and B) are prepared by homogeneous and heterogeneous poly-merization respectively,using 3-acylpyrrole and 4-dimethylaminobenzaldehyde as raw materials. The molecular structure,optical per-formance and aggregation structure of the resulting products are investigated via FTIR,UV-Vis,XRD and fluorescence spectrum. UV-Vis spectra indicate that the products possess apparent optical absorption at the visible light range of 430-650nm. Fluorescence spectra show that both of the prodcuts are blue fluoresent materials. XRD patterns suggest that the two products are completely amor-phous.%以3-酰基吡咯和对二甲氨基苯甲醛为原料，采用均相聚合法和非均相聚合法分别制备了两种可溶性的聚吡咯甲烷衍生物(聚合物A和B)。利用红外光谱、紫外-可见吸收光谱、荧光光谱和X射线衍射谱对产物的分子结构、光学性能和聚集态结构进行了表征和分析。紫外-可见吸收光谱显示，所制备的产物在430~650nm可见光范围内均有明显的吸收。荧光光谱表明，两种聚合产物均为蓝色荧光材料。 X射线衍射谱表明，两种聚合物的聚集态结构均为完全非晶态。
