Abstract
A copper (II) complex of azo-dye (Cu-1) has been synthesized by the reaction of 1-(2-pyridylazo)-2-naphthol (1) with copper (II) chloride. The complex Cu-1 is able to selectively sense hydrogen sulfide over other anions followed by the release of compound 1 to give a remarkable change of UV-vis absorption at neutral pH in aqueous solution.
摘要
通过 1-(2-吡啶偶氮)-2-萘酚（1）与氯化铜（II）的反应，合成了偶氮染料的铜（II）配合物（Cu-1）。配合物 Cu-1 能够选择性地识别硫化氢，而不是其他阴离子，随后释放出化合物 1，在中性 pH 值的水溶液中引起显著的紫外-可见吸收变化。
