文摘

Two novel donor-蟺-acceptor chemosensors, exTTF-DPA and exTTF-ADPA, based on 蟺-extended tetrathiafulvalene (exTTF) and di(pyridine-2-ylmethyl)amine (DPA) were synthesized and used as optical and electrochemical chemosensors for copper(II). The results showed that they possess specific selectivity for copper(II) in the presence of other competing metal ions (Zn²⁺, Sn²⁺, Pb²⁺, Pd²⁺, Hg²⁺, Al³⁺, Fe³⁺, Ag⁺, Co²⁺, Ni²⁺) in acetonitrile. Upon the addition of Cu²⁺, the solution color changed from yellow to orange, the cyclic voltammograms changed dramatically and the fluorescence quenched completely.
