| Abstract: | The 1,3,5-triazine diphosphine oxide ligands with donor-acceptor properties formed strong complexes with europium(III) ion in acetonitrile. Spectrophotometric titrations and mass spectra indicated that two ligands coordinated to one europium ion. The stability constants varied from 11.64 to 14.60 (log β). Binary complexes exhibited rather weak luminescence in solution. 1,3,5-triazine diphosphine oxides engaged as co-ligands in Eu(III) (2-thenoyltrifluoroacetonate)3 complex contributed to the overall photoluminescence and allowed for excitation with longer wavelengths than the parent complex. |
