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.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 Cr^3＋, Cu^2＋ and Hg^2＋, 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 Cr^3＋.
