摘要:
以邻苯二甲酸酐和偏苯三酸酐为配体,尿素,钼酸铵,氯化镝等为原料,采用固相法合成酞菁镝及四酰胺基酞菁镝配合物,通过紫外-可见光谱和红外光谱对酞菁镝配合物及四酰胺基酞菁镝配合物进行了表征分析。通过对比稀酞菁镝和四酰胺基酞菁镝的紫外光谱发现了镝离子的引入使得酞菁Q带吸收发生蓝移,酰胺基引入使酞菁镝Q带吸收发生红移。测定酞菁镝配合物在582 nm、四酰胺基酞菁镝配合物在580 nm处具有良好的荧光发射,他们的荧光光谱都有相似的形状,有较小的stokes位移,通过对比对发现引入酰胺基的四酰胺基酞菁镝配合物比酞菁镝配合物的荧光强度高2~3倍,发现酞菁对镝离子的能量传递。

Abstract: The phthalocyanine dysprosium and the amido functionalized phthalocyanine dysprosium com-plexes were synthesized by solid phase method by reacting phthalic anhydride or trimellitic an-hydride, urea, ammonium molybdate and dysprosium chloride in one pot synthesis. Their struc-tures were identified by UV spectrum and infrared spectrum. It is found that the introduction of dysprosium ion makes the phthalocyanine Q band absorption blue shift, whereas the existence of amide group makes the phthalocyanine dysprosium Q band absorption red shift. The phthalocya-nine dysprosium complex at 582 nm and tetra amide phthalocyanine dysprosium complex at 580 nm both have good fluorescence emission, and fluorescence spectra are in similar shape, with small stokes displacement. The fluorescence intensity of tetra amide phthalocyanine complex of dysprosium is 2 - 3 times higher than dysprosium phthalocyanine compound. The energy transfer of phthalocyanine to dysprosium has been found.
