Abstract

Near-IR emission of novel Yb(III) complexes with phenanthroline derivertives, bis(phenanthroline)-tris(bis-perfluoromethanesurfonyliminate) ytterbium [Yb(pms)₃(phen)₂] and dipyridophenazine- tris(bis-perfluoromethanesurfonyliminate)ytterbium [Yb(pms)₃(dip)] are studied in dimethylsulfoxide [DMSO-d₆]. The emission quantum yields of Yb(pms)₃(phen)₂ and Yb(pms)₃(dipy- phenazine) excited at 940 nm (²F_7/2-²F _5/2 transition) were found to be 7.4 and 9.1%, respectively. We successfully observed the photosensitized near-infrared emission from the Yb(III) complexes upon excitation of the aromatic ligands. The energy transfer efficiencies of Yb(pms)₃(phen)₂ and Yb(pms) ₃(dip) excited at 310nm (π-π* transition) were evaluated to be 9.1 and 4.0%, respectively.
