文章考察了 Fe3+、Ag+、Pd2+、Zn2+、Mn2+、Na+等金属离子对聚[2-甲氧基-5(5’-羧基戊氧基)对苯乙炔](MDP-PPV)荧光性质的影响.发现 Fe3+使 MDP-PPV 荧光猝灭增强,而 Ag+、Pd2+、Zn2+、Mn2+等金属离子对 MDP-PPV 的荧光光谱影响很小.结果表明共轭高分子聚[2-甲氧基-5(5’-羧基戊氧基)对苯乙炔]可用于有效识别 Fe3+的荧光化学传感器.

The effect of metal ions such as Fe3+, Ag+, Pd2+, Zn2+, Mn2+, Na+ on the fluorescence of poly[2- methoxyl-5(5’-carboxy pentyloxy)] (MDP-PPV) was investigated. Among which Fe3+ could enhance the fluorescence quenching of PPV derivative while other metal ions such as Ag+, Pd2+, Zn2+, Mn2+ had little influence on the fluorescence spectrum of PPV derivative. The results show that the conjugated polymer poly [2-methoxyl-5(5’-carboxy pentyloxy)] could be used as fluorometric chemosensor sensitive to Fe3+.
