透過鑭系雙(三甲基矽基)胺 (Tris[N, N-bis-(trimethylsilyl)amide] Lanthanide, Ln(HMDS)3, Ln= Pr3+, Eu3+, Gd3+, Yb3+) 與含有三個氧原子的二(2-羥基-3, 5-二叔丁基苯基)甲酮 (bis(2-Hydroxy-3,5-di-t-butylphenyl) methanone, H2DHBP-tBu)反應後得到雙核的鑭系錯合物形成Ln2(DHBP-tBu)3 (Ln= Pr3+, Eu3+, Gd3+, Yb3+)。在合成Yb(HMDS)3 時，通過純化方式的改變，進一步與配基反應時能夠得到單核的Yb(DHBP-tBu)3Na3(THF)3金屬錯合物。並且對這一系列的錯合物進行性質鑑定，包含質譜、紅外光譜、紫外-可見光吸收光譜、放光光譜，與晶體結構進行比較。在單核與雙核鐿錯合物的放光光譜中，在近紅外光波段可觀察到尖銳且明顯地Yb(III) f-f 軌域躍遷中2F5/2→2F7/2的特徵峰，其絕對量子產率分別為1.54%與1.69%。以Yb(DHBP-tBu)3Na3(THF)3為基底，進一步與同金屬和異金屬鹽類反應，分別能夠得到同核錯合物Yb2(DHBP-tBu)3與異核錯合物GdYb (DHBP-tBu)3。此外也使用將三氧配基延伸後含有五個氧的配基(5-(叔丁基)-2-羥基-1,3-苯基)雙((3, 5-二叔丁基-2-羥基苯基)甲酮) (5-(tert-butyl)-2-hydroxy-1,3-phenylene)bis((3,5-di-tert-butyl-2-hydroxyphenyl)methanone), H3THBP-tBu)與Yb(HMDS)3反應得到三核錯合物，並探討其結構。

Lanthanide complexes have attracted much attention recently and have shown great potential applications in coordination polymer and magnetic functional material owing to their various coordination number, magnetic and photophysical properties. Herein, binuclear lanthanide complexes [Ln2(DHBP-tBu)3] (H2DHBP-tBu = Bis[bis(2-Hydroxy-3,5-di-t-butylphenyl)methanone ; Ln = Pr3+, Eu3+, Gd3+, Yb3+) and one alkali metal lanthanide complex [Ln(DHBP-tBu)3M3(THF)3] (M = Na+; Ln = Yb3+) were obtained by using Ln(HMDS)3 and Na(HMDS) as starting materials.
These lanthanide complexes were fully characterized through single-crystal X-ray diffraction associated with the mass spectrum and elemental analysis. Their photophysical properties were investigated by using UV-Vis spectroscopy and photoluminescence spectroscopy, while their magnetic properties were studied by the superconducting quantum interference device (SQUID).
[Yb2(DHBP-tBu)3] and [Yb(DHBP-tBu)3Na3(THF)3] showed emission peaks at 984 and 979 nm, respectively, which were assigned to the characteristic 2F5/2 → 2F7/2 transition of Yb3+. Their absolute quantum yield were 1.54% and 1.69% in solid state.
The [Ln2(DHBP-tBu)3] complexes crystallize in the trigonal system with space group R"3" ̂c. The geometry around the each Ln3+ metal center shows a slightly distorted.
