摘要
合成了[Ru(bpy)3]2+和Eu(TTA)3Phen两种探针分子,并将两者与甲基丙烯酸甲酯(MMA)混合,在引发剂BPO作用下进行聚合,获得具有温度响应性能的([Ru(bpy)3]2+-Eu(TTA)3Phen)/PMMA温敏漆。采用IR、紫外吸收光谱和荧光光谱对探针分子的结构及温敏漆的荧光特性进行了表征。红外光谱和紫外吸收光谱表明:Ru与2,2'-联吡啶分子通过双氮配位,有O→Eu配位键形成。荧光光谱表明:温敏漆样品的温度猝灭性能较好,并且在不同温度范围内测温灵敏度不同,由452 nm激发时,温敏漆样品在25~45℃范围内测温灵敏度高,最强的荧光发射峰位于584 nm;由342 nm激发时,在45~65℃范围内测温灵敏度高,最强的荧光发射峰位于612 nm。
Two kinds of luminophore molecules were prepared by using RuC13,2,2'-bipyridyl, HTFA, etc. as raw materials. The ( [ Ru (bpy) 3 ] 2 + -Eu ( TFA ) 3 Phen )/PMMA temperature sensitive paint (TSP) was obtained when the two kinds of luminophore molecules were doped into the PMMA. The two kinds of luminophore molecules and the TSP were characterized by FTIR, UV-vis and fluorescence spectra. IR and UV absorption spectrum spectra in- dicated that the coordination bond was formed between Ru ion and 2,2'-bipyridyl, and O→Eu coordination bond was also formed. The fluorescence spectroscopy indicated that the temperature quenching properties of TSP samples were good, and the temperature measure sensitivity was different at different temperature. And the temperature measure sensitivity was enhanced when the TSP was excited by 452 nm in 25 ~ 45 ℃, the strongest emission peak was 584 nm, and the temperature measure sensitivity the strongest emission peak was 612 nm was improved when the TSP was incited by 342 nm in 45 - 65 ℃, the strongest emission peak was 612 nm.
