摘要
通过4-(2-二茂铁乙炔基)苯胺与水杨醛缩合反应得到一种新的含二茂铁基水杨醛席夫碱1,并研究了其对不同金属离子电化学及紫外-可见光谱的识别性质。结果表明,1对Cr3+有很好的紫外-可见光谱及电化学信号响应:其位于467nm的Fe(Ⅱ)→Cp的荷移光谱红移至502nm,同时Fe(Ⅲ)/Fe(Ⅱ)电位发生了~20mV的阳极移动。
A new ferrocene-containing salicylaldehyde Shiffe-base, 1, was synthesized by coupling 4-(2-fer- rocenylethynyl) phenylamine with salicylaldehyde. Its metal ions recognition ability was investigated by UV-Vis spectrometry and cyclic voltammetry (CV). Among various metal ions, 1 shows exclusive UV-Vis and electrochemical response to Cr3+ with a red shift from 467 to 502 nm for its low energy Fe(Ⅱ) →Cp charge transfer and a -20 mV positive shift of its Fe( Ⅲ)/Fe( Ⅱ) potential.
