-
Two ternary complexes Eu(TTA)3L and Eu(BTA)3L (where TTA=thenoyltrifluoroacetone, BTA=benzoyltrifluoroacetone, L=4,5 diazafluorene 9 one) have been synthesized and characterized by elemental analysis, IR, UV and fluorescence spectrum analyses. The results showed that in methyl cyanide the complexes gave a higher fluorescence intensity.
