摘要
利用聚对苯二甲酰氯对聚乙二醇端基进行改性,制备出了聚乙二醇端基活化产物PEG-PTC,然后将其作为配体,通过化学键连接上功能性的发光基团(发光基团的构成主要以稀土铕为中心),合成了带有新型配体PEG-PTC的和1,10-邻菲口罗啉的稀土铕-聚乙二醇型配合物。通过配体、配合物的红外光谱、DSC、TG等的测试,对其组成、结构和性能进行分析。结果表明,含有新型配体PEG-PTC的稀土铕-聚乙二醇型的配合物不仅具有相变功能,同时具有优异的荧光特性,新型配体与稀土离子的激发态能级间具有较好的能级匹配,并且具有良好的热稳定性。
A novel active end-group of PEG- TPC was prepared via the end-groups of polyethylene glycol （PEG） modified by terephthaloyl chloride （TPC）. And then, PEG-TPC as a ligand linked up to functional light-emitting group through chemical bond, and rare-earth europium （Eu3 ＋ ） is the main component of the luminescence group to pose. Finally, the complex of Eu- PEG were synthesized with novel ligands （PEG-TPC） and 1, 10- phenanthroline. The composition, structure and properties of the novel phase change luminescence polymer materials were characterized through the Fourier transform infrared spectrum（FT-IR）, differential scanning calorimetry （DSC）, thermogravimetry analysis（TG） and other means of testing of the ligand and complex. The results show that the complexes of Eu-PEG with new ligand （PEG-PTC） have phase change properties, and excellent luminescent property. Energy levels between the excited state of new ligand and the rare earth ion have a good energy level matching, and have excellent thermal stability.
