| PHOTOPHYSICAL PROPERTIES OF NOVEL RARE EARTH COMPLEXES WITH ETHYL 4-HYDROXY-7-TRIFLUOROMETHYL-3-QUINOLINECARBOXYLATE | |
| 摘要: 首次合成了五种新型希土(Eu3+, Tb3+, Gd3+, Sm3+, Dy3+)配合物。配体为带有喹啉环的4-羟基-7-三氟甲基-3-喹啉基甲酸乙酯。并用元素分析、红外光谱和热分析方法确定了配合物的组成。通过测定钆配合物的低温磷光光谱表明4-羟基-7-三氟甲基-3-喹啉基甲酸乙酯的三重态能级为22000 cm-1。配合物的光物理性质表明配体的三重态能级适于希土Eu3+, Sm3+, Dy3+和Tb3+，特别是Tb3+的发光。 | |

| Abstract: Five nove rare earth (Eu3+, Tb3+, Gd3+, Sm3+ and Dy3+) complexes with ethyl 4-hydroxy-7-trifluoromethyl-3-quinolinecarboxylate which contains one quinoline cycle were synthesized and characterized by elemental analysis, IR spectrum and thermal analysis. The triplet state energy of ethyl 4-hydroxy-7-trifluoromethyl-3-quinolinecarboxylate was determined to be 22000 cm-1 with the measurement of low temperature phosphorescence spectrum of corresponding gadolinium complex. The photophysical properties of these complexes indicated that the triplet state energy of the ligand is suitable for the luminescence of Eu3+, Sm3+, Dy3+ and Tb3+, especially of Tb3+. | |
