Novel EuIII complexes with bidentate phosphine oxide ligands containing a bipyridine framework, i.e., [3,3′-bis(diphenylphosphoryl)-2, 2′-bipyridine]tris(hexafluoroacetylacetonato)europium(III) ([Eu-(hfa) 3(BIPYPO)]) and [3,3′-bis(diphenylphosphoryl)-6,6′- dimethyl-2,2′-bipyridine]tris(hexafluoroacetylacetonato)europium(III) ([Eu(hfa)3(Me-BIPYPO)]), were synthesized for lanthanide-based sensor materials having high emission quantum yields and effective chemosensing properties. The emission quantum yields of [Eu(hfa)3(BIPYPO)] and [Eu(hfa)3(Me-BIPYPO)] were 71 and 73%, respectively. Metal-ion sensing properties of the EuIII complexes were also studied by measuring the emission spectra of EuIII complexes in the presence of ZnII or CuII ions. The metal-ion sensing and the photophysical properties of luminescent EuIII complexes with a bidentate phosphine oxide containing 2,2′-bipyridine framework are demonstrated for the first time.
