The first example of a new Hg(2+)-sensing system based on the structures of complexes is reported. The system uses a combination of a new chiral bidentate ligand and CD spectroscopy. Significant CD spectral changes are observed when Hg(2+) is added, whereas no CD spectral changes are observed in the cases of Li(+), Na(+), K(+), Mg(2+), Ca(2+), Mn(2+), Fe(2+), Co(2+), Ni(2+), Cu(2+), Zn(2+), Rb(+), Ag(+), Cd(2+), La(3+), Gd(3+), and Pb(2+).
报道了首例基于配合物结构的新型 Hg(2+) 传感体系。该体系采用一种新型手性双齿配体与圆二色谱(CD 光谱)相结合的方法。当加入 Hg(2+)时,观察到显著的 CD 光谱变化,而在 Li(+)、Na(+)、K(+)、Mg(2+)、Ca(2+)、Mn(2+)、Fe(2+)、Co(2+)、Ni(2+)、Cu(2+)、Zn(2+)、Rb(+)、Ag(+)、Cd(2+)、La(3+)、Gd(3+)和 Pb(2+) 存在的情况下,CD 光谱没有变化。
