摘　　要：以氧化铕(Eu_2O_3)、甲基丙烯酸(MAA)、水杨酸(HSal)、肉桂酸(HCA)和菲咯啉(Phen)为原料制备了Eu(MAA)3Phen、Eu(Sal)_3Phen和Eu(CA)_3Phen探针分子,并将不同探针分子分别加到甲基丙烯酸甲酯(MMA)中,在过氧化苯甲酰(BPO)引发下聚合,制得一系列温敏漆样品。采用红外光谱仪、荧光光谱仪和扫描电子显微镜对探针分子的结构、发光性能、形貌和温敏漆的温度猝灭性能进行了表征,研究了不同配体对探针分子发光性能和温敏漆温度猝灭性能的影响。结果表明,探针分子Eu(MAA)3Phen的荧光强度明显高于Eu(Sal)_3Phen和Eu(CA)_3Phen,相应的3种温敏漆Eu(MAA)3Phen/PMMA、Eu(CA)_3Phen/PMMA和Eu(Sal)_3Phen/PMMA均有良好的温度猝灭特性,但是对比发现在55~65℃范围内Eu(MAA)3Phen/PMMA和Eu(CA)_3Phen/PMMA温敏漆的灵敏度较高,而在35~45℃范围内Eu(Sal)_3Phen/PMMA温敏漆的灵敏度较高,可见不同的温敏漆适用于不同的温度范围。Probe molecules of Eu（MAA）3Phen, Eu（Sal）3Phen and Eu（CA）3Phen were prepared by using europium oxide（Eu2Oa）, methaerylate（MAA）, salicylic aeid（HSal）, einnamie aeid（HCA） and phenanthroline（Phen）. A series of temperature sensitive paints （TSPs） were obtained by the polymerization of different probe molecules, methyl methaerylate（MMA） and the initiator of benzoyl peroxide（BPO）. The structure, morphology, luminescence property of probe molecules and the temperature quenching property of TSPs were characterized by infrared spectrometer, fluorescence spectrometer and scanning electron microscopy. The effect of different ligands on the luminescence property of probe molecules and the temperature quenching property of TSPs were studied. It is indicated that the fluorescence intensity of Eu（MAA）3Phen is obviously higher than that of Eu（Sal）3Phen or Eu（CA）3Phen, and the temperature quenching properties of the three TSPs are good. The temperature sensitivity of Eu （MAA）sPhen/ PMMA and Eu（CA）3Phen/PMMA is higher in 55-65 ℃. However, the temperature sensitivity of Eu（Sal）3Phen/PMMA is higher in 35-45℃. That is to say, different TSPs can be used in different temperature ranges.
