Synthesis and Characterization of A Dinuclear Europium Complex
2007年
A dinuclear Eu(Ⅲ) complex Eu2(DBM)6TPPD (Hexa(dibenzoyl-methanido)-(N, N, N, N-tetra(2-pyridyl)-1, 4-phenylenediamine)-dieuropium(Ⅲ)) was synthesized by employing DBM (dibenzoylmethane) and TPPD (N, N, N, N-Tetra(2-pyridyl)-1, 4-phenyl-enediamine) as sensitizing ligands for the Eu(Ⅲ) ion and a bridging ligand, respectively. The analysis of the absorption, excitation, and emission spectra of the dinuclear complex along with a comparison with analogous mononuclear complex containing the same β-diketone ligands and 1, 10-phenanthroline (phen) suggests that the dinuclear complex follows the luminescence mechanism of general Ln(Ⅲ) complexes.

Photoluminescence properties of dinuclear lanthanide complexes in visible and near-infrared region被引量:1
2010年
Several dinuclear lanthanide complexes of Ln2(HTH)6TPPHZ (Ln=Eu, Sm, Er, Nd, Yb, Ho; TPPHZ=Tetrapyrido (3,2-a:2’,3’-c:3’,2'-h:2'’,3’'-j) phenazine; HTH=4,5,5,6,6,6-heptafluroro-1-(2-thienyl)hexane-1,3-dione were synthesized and their photoluminescence properties were investigated. After ligand-mediated excitation, all the complexes showed the characteristic luminescence of the corresponding Ln(III) ions in the visible and NIR regions attributed to energy transfer from the ligands to the metal center. For Eu...

Synthesis and photoluminescence of a dendritic europium complex with carbazole moieties被引量:2
2008年
A novel dendritic europium complex containing grafted carbazole units as functional peripheries was synthesized and characterized. The Foerster energy transfer from the peripheries of carbazole units to β-diketonate as well as from the hgands to the central Eu(Ⅲ) ions in the complex was demonstrated. Under the excitation of carbazole units and β-diketonate, characteristic red emission peaks at 612 nm with four shoulders due to the Eu(Ⅲ) ion transition of 5^D0→7^FJ (J=0-4) were observed for the complex.

含咔唑基团铕配合物的合成和荧光性能研究被引量:3
2009年
将具有良好空穴传输能力的咔唑基团引入到一个新型β-二酮配体CCHPD(1-[(6-(9H-carbazol-9-yl)hexoxy)phenyl]-3-[(6-(9H-carba-zol-9-yl)-hexoxy)-phenyl]-1,3-d ione)中,然后分别以1,10-邻菲咯啉(Phen)和4,7-二苯基-1,10-邻菲咯啉(Bath)为中性配体合成了两种相应的树枝状铕配合物。配合物在230-350 nm的紫外光激发下都可以发射出非常强的铕离子特征红光(^5D0→^7FJ(J=0-4)),主发射峰在612nm。含脂肪链的咔唑基团在铕离子的周围形成了"光吸收天线",拓宽了β-二酮的吸收范围,屏蔽溶剂分子对稀土离子荧光猝灭效应,还可以有效地提高铕配合物的空穴传输能力,对于提高稀土配合物的电致发光性能方面有重要的意义。
