In order to obtain new NIR luminescent lanthanide complexes free of C-H and C-O bonds the perfluorinated 2-mercaptobenzothiazolate (mbt^F) was used as organosulphide antenna ligand and the perfluorinated triphenylphosphine oxide (TPPO^F) was used to saturate the coordination sphere of the lanthanide ion. Targeted complexes Ln(mbt^F)₃(TPPO^F)₂ (Ln = Nd(1), Er(2) and Yb(3)) were synthesized in high yields from respective silylamides Ln[N(SiMe₃)₂]₃, Hmbt^F and TPPO^F using dry toluene as a solvent. Upon near UV light excitation the compounds 1–3 in the solid state showed an intense NIR photoluminescence which is characteristic for corresponding lanthanide ions. This luminescence was studied at a room temperature by time-resolved methods. The study revealed the presence of intermediate f-f transitions in the time resolved photoluminescence spectrum of 2. The measured lifetimes of Nd and Er NIR emission in 1 and 2 are 39.5 and 53.5 μs respectively. It was found that these lifetimes are among the longest for neat erbium and neodymium complexes with organic ligands.

为了获得新的不含 CH 和 CO 键的 NIR 发光镧系元素配合物，全氟化 2-巯基苯并噻唑 (mbt ^F ) 用作有机硫化物天线配体，全氟化三苯基氧化膦 (TPPO ^F ) 用于饱和镧系离子的配位球. 从各自的甲硅烷基酰胺 Ln[N(SiMe ₃ ) ₂ ] ₃以高产率合成了目标配合物 Ln(mbt ^F ) ₃ (TPPO ^F ) ₂ (Ln = Nd( 1 )、Er( 2 ) 和 Yb( 3 )) ， Hmbt ^F和 TPPO ^F使用干燥的甲苯作为溶剂。在近UV光激发的化合物1 - 3在固体状态表现出强烈的光致发光NIR其是用于相应的镧系元素离子的特性。通过时间分辨方法在室温下研究这种发光。该研究揭示了2的时间分辨光致发光光谱中存在中间f - f跃迁。1和2中Nd 和 Er NIR 发射的测量寿命分别为 39.5 和 53.5 μs。发现这些寿命是纯铒和钕与有机配体配合物最长的。
