在2×10-3Pa真空度下,以酞菁铜(CuPc)、均苯四甲酸酐(PMDA)和二氨基二苯醚(ODA)为原料,通过控制三源单体的加入摩尔计量、加热时间和其沉积速率,在玻璃衬底上合成了含酞菁铜的聚酰胺酸,再经150～200℃真空加热亚胺化1h后得到了成膜性良好的均匀含酞菁铜聚酰亚胺薄膜。红外谱图证实了所合成产物的结构,紫外吸收分析表明含酞菁铜聚酰亚胺薄膜在可见光区、近红外区具有较强的吸收,热失重分析表明所制备的含酞菁铜聚酰亚胺具有良好的热稳定性能;简并四波混频方法测得薄膜的三阶非线性极化率为1.984×10-9esu,表现出良好的三阶非线性特性。
Under the vacuum degree of 2 × 10-3Pa, copper phthalocyanine (CuPc), pyromellitic dianhydride (PMDA) and diaminodiphenyl ether (ODA) were used as raw materials to control the molar amount of the three- Time and deposition rate of copper polyphthalocyanine containing copper phthalocyanine synthesized on a glass substrate, followed by heating at 150 ~ 200 ° C under vacuum imidization 1h obtained a good film-forming uniform copper phthalocyanine containing polyimide Amine film. The infrared spectrum confirmed the structure of the synthesized product. UV absorption analysis showed that the copper phthalocyanine-containing polyimide film had a strong absorption in the visible and near-infrared regions. The thermogravimetric analysis showed that the prepared copper phthalocyanine- The imine has good thermal stability. The third-order nonlinear polarizability of the film measured by degenerate four-wave mixing method is 1.984 × 10-9esu, showing good third-order nonlinearity.
