摘要
为改善聚酰亚胺材料的光学性能,采用引入非共轭基团和不对称侧基基团的方法,制备了7种聚酰亚胺分子,并对合成的聚酰亚胺进行了核磁表征和紫外-可见光谱测试。结果表明,由于Suzuki偶联反应引入的芳基基团的各向异性和不同的共轭效应,导致聚酰亚胺的特征峰核磁氢谱化学位移和最大吸收峰波长存在差异。
In order to improve the optical properties of polyimide materials,seven polyimide molecules were prepared by introducing nonconjugated groups and asymmetric side groups,and the synthesized polyimides were characterized by nuclear magnetic resonance and ultraviolet-visible spectra.The results showed that there were differences in the characteristic peak nuclear magnetic resonance chemical shift and maximum absorption peak wavelength of polyimides due to the anisotropy and different conjugation effects of aryl groups introduced by Suzuki coupling reaction.
