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 .
