摘要
通过溶液聚合的方法以氮三乙酸(NTA),4,4′-二氨基二苯醚(ODA)为原料合成了高度支化聚芳酰胺(PNOA),并以PNOA为配体与EuCl3配位制备出Eu/PNOA高分子发光材料。采用红外光谱分析了PNOA和Eu/PNOA的结构,用热重(TG)分析了Eu/PNOA的热稳定性,用紫外及荧光光谱法表征了它们的光学性能。结果表明,PNOA与稀土离子Eu3+发生了配位作用,Eu/PNOA在被350nm的紫外光激发后发出616nm的红色荧光,是一种具有潜力的高分子功能材料。
Nitrilotriacetic acid （NTA） was used to react with 4,4＇-diaminodiphenyl ether （ODA） by solution polymerization to synthesize highly branched aromatic polyamide （PNOA）. Eu/PNOA was successfully prepared by using PNOA as complex containing EuCl3. The structure of the product PNOA and Eu/PNOA was characterized by Fourier transform infrared spectrum（FT-IR）. The thermogravimetic analysis （TGA） was used to conduct the thermal stability. The optical property was characterized by UV-visual and fluorescence spectroscopies. The results show that Eu3＋ ion is incorporated with PNOA,and Eu/PNOA can emit the red fluorescence at 616 nm after by excited by 250 nm ultraviolet ray.
