合成和表征了基于2－苯基－4[（2－噻吩）乙烯基]吡啶的新型联吡啶钌配合物Ru－1，利用紫外－可见吸收光谱研究了Pb2＋，Co2＋，Ag＋，Mn2＋，Ni2＋，Cd2＋等重金属离子对Ru－1光谱的影响。结果表明：仅Cu2＋， Hg2＋的加入可引起Ru－1乙腈溶液颜色的变化，分别由红黑色变成无色及黄色，故Ru－1可用于CH3 CN溶液中检测并肉眼识别Cu2＋，Hg2＋。

A new cyclometallated ruthenium complex Ru-1 based on 2-phenyl-4 [ ( 2-thiophene ) vinyl ] pyridine was synthesized and characterized.The effect of heavy metal ions such as Pb2+, Co2+, Ag+, Mn2+, Ni2+, Cd2+ on its absorption was studied by UV-Vis spectroscopy.The results showed that the addition of Cu2+and Hg2+could lead to color changes of the Ru-1 in acetonitrile solution from reddish black to colorless and yellow, respectively.Therefore Ru-1 can be used as a“naked-eye” sensor for Cu2+and Hg2+in CH3 CN solutions.
