合成了Eu(Ⅲ)与偏苯三甲酸(TLA)、2-噻酚甲酰三氟丙酮(HTTA)和邻菲罗啉(Phen)形成的两个新的四元配合物。运用元素分析、红外光谱、扫描电镜、热重与荧光光谱等手段对它们进行了系统的表征。研究结果表明,偏苯三甲酸与2-噻酚甲酰三氟丙酮Eu(Ⅲ)和邻菲罗啉形成的四元配合物,具有比偏苯三甲酸Eu(Ⅲ)和邻菲罗啉形成的三元配合物更强的荧光强度与更宽的紫外激发,比配合物Eu(TTA)3Phen更好的热稳定性。得到了两种热稳定性较好的鲜艳红色荧光材料。
Two novel quaternary complexes of Eu (Ⅲ) with trimellitic acid (TLA), 2-thiophenoxytrifluoroacetone (HTTA) and phenanthroline were synthesized. They were systematically characterized by elemental analysis, infrared spectroscopy, scanning electron microscopy, thermogravimetry and fluorescence spectroscopy. The results showed that the tetranuclear complexes of trimellitic acid with 2-thiophenoxytrifluoroacetone Eu (Ⅲ) and 1,10-phenanthroline were more stable than Eu (Ⅲ) and o-phenanthroline The ternary complex with stronger fluorescence intensity and wider UV excitation has better thermal stability than Eu (TTA) 3Phen complex. Two bright red fluorescent materials with better thermal stability were obtained.
