摘　　要：合成了丙二硫醚桥联2个乙酰丙酮的双β-二酮分子1,3-二(3-硫醚基-2,4-戊二酮基)丙烷(L1),以此为配体与镍(Ⅱ)作用得到配合物,通过元素分析和摩尔电导分析方法确定了镍(Ⅱ)配合物的化学组成,比较分析了配位前后的游离配体与配合物的红外及紫外吸收光谱,采用紫外光谱滴定法对配体L1与Ni(Ⅱ)离子在溶液中的配位行为进行了模拟研究,并进行金属离子液膜传输实验考察了L1对Ni(Ⅱ)的液膜传输性能。结果显示,L1通过4个O原子与Ni(Ⅱ)配位成键形成配合物,且对Ni(Ⅱ)具有良好的液膜传输性。The bis-β-diketone molecule incorporating 1,3-propanedithioether bridge between the γ-carbons of respective β-diketone units of 1,3-bis（3-thio-2,4-pentanedionate） propane（L1） had been synthesized,and then L1 as a ligand reacted with Ni（Ⅱ） to form a nickel complex.The formula of Ni（Ⅱ） complex was determined by elemental analysis and molar conductance.The possible coordination mode of complex were concluded by comparison with the IRUV spectral properties of the free ligand and its nickel（Ⅱ）complex.Additionally,the coordination behavior of nickel salts and bis-β-diketone ligand L1 in solutions and the liquid membrane transport property of L1 with Ni（Ⅱ） ion were also investigated by ultraviolet spectroscopy characterisation.The results showed that bis-β-diketone ligand L1 coordinate through four oxygen atoms bonding Ni（Ⅱ）,and L1 had a good liquid membrane transport property for nickel（Ⅱ） ion.
