| 摘要: 以氧化铕（Eu2O3）、对氯苯甲酸（PCBA）、对溴苯甲酸（PBrBA）和菲咯啉（phen）为原料制备了菲咯啉对氯苯甲酸铕[Eu（PCBA）3 phen]、菲咯啉对溴苯甲酸铕[Eu（PBrBA）3phen]两种探针分子，并将这2种探针分子掺杂在甲基丙烯酸甲酯（MMA）中，以过氧化苯甲酰（BPO）为引发剂，制得Eu（PCBA）3phen/PMMA和Eu（PBrBA）3phen/PMMA温敏漆样品。利用红外光谱仪、扫描电子显微镜、紫外-可见分度光度计和荧光光谱仪对探针分子的组成结构、发光性能、形貌和温敏漆的温度敏感性进行了测试分析，研究了不同配体对探针分子发光性能和温敏漆性能的影响。结果表明，Eu3+分别与对氯苯甲酸（PCBA）和对溴苯甲酸（PBrBA）2种主配体配位，并且第二配体菲咯啉（phen）均参与了配位，成功合成了2种配合物。2种配合物均发出Eu3+的特征荧光，其中以PBrBA为主配体的菲咯啉铕三元配合物具有更好的发光性能。此外，基于这2种探针分子制备的温敏漆在50~90℃范围内均具有温度猝灭性能，以Eu（PCBA）3phen为探针制成的温敏漆温度敏感性更强。 |

| Abstract: Europiumsesquioxide (Eu2O3), parachlorobenzoic-acid (PCBA), parabromobenzoic acid (PBrBA) and o-phenanthroline (phen) were used as raw materials to synthesize two kinds of probe molecules Eu(PCBA)3phen and Eu(PBrBA)3phen. And these two probe molecules were doped in the substrate of polymethyl methacrylate (MMA), benzoyl (BPO) peroxide as initiator, to prepare two kinds of temperature sensitive paints. The infrared spectrometer, ultraviolet spectrometer, scanning electron microscope and fluorescence spectrometer were utilized to analyze the structure, fluorescence properties, morphology and temperature sensitivity of the probes, respectively. Meanwhile the effects of different ligands on the fluorescence properties of the probe molecules and the relevant temperature sensitive paints were studied. The results showed that Eu3+ was coordinated with the main ligand of PCBA and PBrBA, respectively, and the second ligand phen was involved in the coordination, which confirms that two new complexes were synthesized. Both complexes emit characteristic fluorescence of Eu3+, and the ternary complex of phenanthroline europium with PBrBA as the main ligand has better fluorescent properties. Furthermore, the temperature sensitive paints based on these two probes both had temperature-quenching performance in a range of 50~90℃, and the temperature sensitive paint doped with Eu(PCBA)3phen had better temperature sensitivity. |
