Synthesis and optical characterization of Eu(TTA)3(Ph3PO)2

Synthesis and optical characterization of Eu(TTA)3(Ph3PO)2

Coordination compound tris(thenoyltrifluoroacetonato)bis(triphenylphosphine oxide) europium(III) Eu(TTA)3(Ph3PO)2, where TTA is the thenoyltrifluoroacetonate monoanion (C8H5F3O2S), Ph3PO is triphenylphosphinoxide (TPPO), is synthesized. Solutions with different molar ratios of Eu(TTA)3(Ph3PO)2 and t...
