| 摘 要： | 合成了一种含席夫碱基团的二茂铁-蒽二元化合物1, 并研究了其金属离子识别时紫外-可见光谱, 荧光光谱及电化学变化. 在各种金属离子中, 1 对Cr3+, Cu2+及Hg2+显示出多种信号响应识别: 1 位于407 nm 的Fe(II)→Cp 的荷移光谱发生约100 nm 红移, 且颜色由黄色变为红色, 同时使其Fe(III)/Fe(II)电位向阳极移动. 同时, 荧光光谱表明1 仅对Cr3+显示荧光增强效应.

| Abstract: | A new ferrocene-anthracene dyad bearing Schiff base donor,1,has been synthesized and char-acterized.Its metal ions recognition ability was investigated by UV-Vis spectra,emission spectra and cyclic voltammetry(CV).Among various metal ions,1 shows multi-respond to Cr3+,Cu2+ and Hg2+,with a ca.100 nm red-shift of the low energy Fe(Ⅱ)→Cp charge transfer located at 407 nm,which can be observed color change from yellow to red by naked eyes,and an anode shift of the Fe(Ⅱ)/Fe(Ⅲ) potential.In addition,1 shows exclusive emission-on sensing to Cr3+. |
