Microwave-assisted synthesis of ternary lanthanide(2-thenoyltrifluoroacetone)3(triphenylphosphine oxide)2 complexes

We report here the fast synthesis by microwave assisted technique of four ternary Ln(TTA)3(TPPO)2 complexes, where Ln?=?La(III), Eu(III), Tb(III) and Tm(III), TTA?=?2-thenoyltrifluoroacetone, and TPPO?=?triphenylphosphine oxide, which are of interest in luminescence applications. Using this method, the reaction time was decreased to one minute with minimal purification step and the yields are comparable to literature values. The target complexes were characterized using 1H, 13C, 19F, 31P NMR and FTIR spectroscopy, MALDI-TOF mass spectrometry and single-crystal X-ray diffraction. Further, we discuss here a hitherto unreported extensive network of hydrogen bonding interactions present in these complexes.

Synthesis and electroluminescent property of ternary complexes Eu(TTA)3M

Three kinds of rare earth ternary complexes of Eu3+ with HTTA and M (M = 5-NO2Phen, 2,2′-Dipy and TPPO) have been synthesized and characterized using various spectral techniques such as elemental analysis, TGA-DTA, IR, UV and fluores

Luminescent properties of complexes Y1-xEux(TTA)3(TPPO)2 in nano-TiO2

A series of HTTA (thenoyltrifluoroacetone) and TPPO (trioctylphosphine oxide) complexes with different molar ratios of Eu3+ to Y3+ has been synthesized. Characterization with XRD, IR, UV, elemental analysis and fluorescence spectroscopy has also been carried out. These results showed luminescence of Eu3+ complex was enhanced after doped with Y3+. The organic-inorganic thin film of complexes Y1-xEux(TTA)3(TPPO)2 in nano-TiO2 was fabricated, and the nano-TiO2 has been used in the luminescence layer to change the luminescence property of complexes Y1-xEux(TTA)3(TPPO)2. It was found that there was an efficient energy transfer process between the ligands and metal ions.

Syntheses, structures and luminescent properties of Sm (III) and Eu (III) chelates for organic electroluminescent device applications

Samarium(III) and europium(III) complexes of the β-diketone ligand (2-thienyl)trifluoroacetylacetone (HTTA) and triphenylphosphine oxide (TPPO) were prepared. The complexes, Sm(TTA)2(TPPO)2NO 3 (1), Eu(TTA)2(TPPO)2NO3H 2O (2), and Eu(TTA)3(TPPO)2 (3) were characterized. Single crystal X-ray diffraction molecular structures of complexes 1 and 3 are presented and some of the crystal parameters for complex 1 are: space group, P1; a = 11.019(4) A?, b = 11.791(6) A?, c = 12.535(5) A?; α = 102.68(3)°, β = 102.06(3)°, γ = 117.75(3)°; for complex 3: space group, P - 1, a = 11.1946(9) A?, b = 12.117(2) A?, c = 23.535(2) A?, α = 80.047(13)°, β = 76.498(7)°, γ = 70.450(9)°. Electroluminescent devices were fabricated by vacuum evaporation. Apart from single layer devices, double and triple layer devices with the following structures: ITO/TPD/Complex 2/Al; ITO/TPD/Complex 3/Al; ITO/TPD/Complex 2/Alq/Al were studied, where N,N-bis(3-methylphenyl)-N,N′-diphenyl-benzidine (TPD) was used as a hole transporting layer and tris(8-hydroxyquinolinate)aluminum (Alq) as an electron transporting layer. The results indicate that single layer devices show very low quantum efficiency, while the double layer devices with a hole transporting layer exhibit enhanced efficiency and a well defined EL spectrum. No significant improvement was observed in the triple layer devices with an additional electron transporting layer.

Characterization of ternary coordination complex of europium with thenoyltrifluoroacetone and triphenylphosphine oxide in situ synthesized in ORMOSIL

By using the in situ synthesis technique, the complex of europium with thenoyltrifluoroacetone (TTA) and triphenylphosphine oxide (TPPO) was confirmed to synthesize in the transparent monolithic ORMOSIL during heat treatment by IR and photoluminescence spectra. The ORMOSIL doped with the Eu-TTA-TPPO in situ complex appears to have rather high luminescence intensity and relative intensity ratio of 5D0→7F2/5 D0→7F1, i.e., better monochromaticity. The emission intensity of the Eu3+ ions in the ORMOSIL heated at 100°C for 24 h increases by a factor of about 1400 compared to that in the no heat treatment sample. Laser excited high-resolution spectra indicate that the molecular structure of the Eu-TTA-TPPO in situ complex is similar to that of the Eu(TTA)3(TPPO)2 complex. The effective site symmetry of the Eu3+ ion in the Eu-TTA-TPPO in situ complex as well as in the Eu(TTA)3(TPPO)2 complex may be C1 or C2 or CS. It is reasonable to suggest that the Eu-TTA-TPPO in situ complex may be Eu(TTA)3(TPPO)2.
