摘要：

A series of near-infrared (NIR) luminescent complexes Ho(dbm)(3)L and Pr(dbm)(3)L [where dbm = dibenzoylmethane; L = 1,10-phenanthroline (phen), 2,2'-bipyridine (bipy), or triphenyl phosphate oxide (TPPO)] were synthesized. Their elemental analyses, crystal structures, fluorescence spectra and luminescent lifetimes were successfully investigated. After ligand-mediated excitation of the complexes, they all show the characteristic NIR luminescence of the corresponding Ln(3+) ions (Ln = Ho, Pr), which can be attributed to efficient energy transfer from the ligands to the central Ln(3+) ions, an antenna effect.
