在本研究中，使用三[N,N-雙(三甲基甲矽烷基)醯胺]鑭系金屬鹼，並以二(3,5-二叔丁基-2-羥基二苯)甲酮做為我們的配基。成功合成出不同金屬的雙核金屬串及三核金屬串，由結構鑑定得知雙核金屬與金屬間距離隨原子半徑遞減，雙核鑭系錯合物也展現出不同的螢光性質，在紅外放射光譜上銩 (Thulium)雙核錯合物具有鑭系元素的紅外放光特徵峰，並有約7 ns的發光壽命。磁性研究上，釹 (Neodymium)、鋱 (Terbium)、銩 (Thulium)、鈥 (Holmium)等雙核錯合物其χMT值在接近2 K下隨溫度而快速下降，表現反鐵磁性的特徵。此外，我們也成功開發三核鑭系金屬串，這是第一個以鑭系金屬為主軸的金屬串。

We uesd the tris[N,N-bis(trimethylsilyl)methyl]lanthanide as the base and tert-butyl-substituted di(3,5-di-tert-butyl-2-hydroxyphenyl)methanone as the ligand to synthesize the lanthanide metal string complexes. We successfully prepared dinuclear metal strings complexes and successfully developed trinuclear lanthanide metal strings. The structural analysis revealed a decreasing distance between two metals with the shrink of atomic radius. lanthanide complexes were known to have unique fluorescent properties. Our dinuclear thulium complexes displayed Near-infrared emission with its lifetime of approximately 7 nanoseconds. In terms of magnetic properties, the rapidly decrease in the χmT value in 2 K indicated an antiferromagnetic behavior for complexes containing neodymium, terbium, thulium and holmium. Furthermore, we successfully developed trinuclear lanthanide metal strings complexes, which will be the first metal string platform based on lanthanide metals.
