摘　　要：通过配体2-醛基-8-羟基喹啉与Yb(ClO4)·6H2O反应,得到8-羟基喹啉-2-甲酸甲酯镱配合物,配体中醛基在甲醇、乙腈溶液中转化为甲酯基,转化后的甲酯基与镱离子配位。配合物为零维单核结构,3个配体对镱离子形成包裹型配合物,并表现出镱离子的近红外荧光性质,固态下的荧光寿命为12.01μs,甲醇溶液中的荧光寿命为10.07μs。Complex 1 has been synthesized by reaction of 2‐aldehyde‐8‐hydroxyquinoline with Yb（ClO4）3 ·6H2O ,the aldehyde of the ligand is translated into methylformate in CH3OH and CH3CN soluting . X‐ray diffraction analysis reveals that complex 1 is unique mononuclear structure . Noticeable , the Yb3＋ ion is wrapped by the three 8‐hydroxylquinolinyl‐2‐methylformates ,which act well as an antenna for complex 1 to promote NIR luminescence of Yb3＋ ions . Complex 1 exhibits essential NIR luminescence of Yb3＋ ion with lifetime of 12.01 μs in solid and 10.07 μs in CH3 OH solution .
