| 摘 要： | 利用羧酸功能化的金属铱配合物(ppy)2Ir(H2dcppy)]PF6与Gd离子配位,合成了d-f配位聚合物纳米线。荧光光谱表明,该纳米线具有良好的磷光发射性质,纳米线相比纯的铱配合物发射光谱有30 nm的蓝移。根据核磁共振成像结果,计算纳米线在溶液中的弛豫率,其r1为4.56 mM-1·s-1,r2为9.52 mM-1·s-1,该纳米线具有较小的r2/r1,可以作为阳性核磁共振成像造影剂。

| Abstract: | Magnetophosphorescent d - f coordination polymer nanoparticles （f - CPPs ） were synthesized by phosphorescent earboxyl- functionalized iridium complexes as building blocks and magnetic Gd （Ⅲ） ions as metallic nodes. Fluorescence spectra showed that the nanowires had good emission properties of the phosphor, compared to the pure nanowires emission spectra of iridium complexes with 30 nm blue shift. According to the results of magnetic -i resonance imaging, the rates of relaxation of nanowires in solution were calculated, which r1 was 4.56 mM ^- 1 . s^- , r2 was 9.52 raM^-1 . s^-1 had a smaller r2/r1 nanowires, and can be used as a positive MRI contrast agent. |
