设计合成了一种Eu
3+
离子功能化的聚合物基稀土杂化探针。利用苯甲酰三氟丙酮(BFA)与镧系Eu
3+
进行配位反应得到配合物Eu(BFA)
3
后再进一步与MMA单体进行聚合制备得到聚合物杂化探针分子Eu⁃(BFA)
3
@PMMA,对Eu(BFA)
3
@PMMA的结构和荧光性能进行了详细的探究,并且将其用于肿瘤标志物唾液酸(SA)的传感检测应用。研究结果表明,SA能对Eu(BFA)
3
@PMMA的荧光产生明显的猝灭效果。此外,在最佳激发波长为325 nm时进行荧光性能对比实验发现Eu(BFA)
3
@PMMA对SA具有较强的选择性和抗干扰能力,且检出限较低。
In this paper, a polymer-based rare earth hybrid probe functionalized by Eu
3+
was designed and synthesized. The coordination reaction between benzoyl trifluoroacetone (BFA) and lanthanide Eu
3+
was used to obtain the complex Eu(BFA)
3
, which was further prepared by polymerization with MMA monomer to obtain polymer hybrid probe Eu(BFA)
3
@PMMA. The structure and fluorescence properties of Eu(BFA)
3
@PMMA were investigated in detail. It is also used in the sensor detection of tumor marker sialic acid (SA). The results showed that SA can produce a significant quenching effect on the fluorescence of Eu(BFA)
3
@PMMA. In addition, fluorescence properties contrast experiments at excitation wavelength of 325 nm showed that Eu(BFA)
3
@PMMA had strong selectivity and anti-interference ability for SA, and the detection limit was low.
