制备了一系列10个四齿1-羟基-吡啶-2-酮(1,2-HOPO)配体和相应的八配位光致发光Eu(III)和Sm(III)配合物。通常,配体的线性(nLI)脂族连接基长度不同,在双齿1,2-HOPO螯合剂单元之间为2至8个亚甲基单元。发现光致发光量子产率(Φtot)随连接子长度而变化,并且对于Eu(III)和Sm(III)配合物观察到相同的趋势。的2LI和5LI桥接的配合物是最亮的(Φ TOT xε)。密度泛函理论(DFT)计算进一步支持了通过X射线衍射(XRD)观察到的2LI和5LI配合物之间的配体包裹方式的变化。双峰ΦtotEu(III)和Sm(III)配合物的趋势可以通过随着桥(n LI)长度的增加而改变配体的包裹方式来合理化。
