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.
