Study on Synthesis, Characterization and Fluorescence of Ternary Complexes Anthraquinone-2,6-disulfonic Acid Disodium Salt

磺酸类物质的配合物与羧酸类物质相比较研究报道很少,但其可做为潜在的液晶和非线性光学材料。在合适的反应条件下,磺酸类物质也能生成特定的功能配合物。由2,6-蒽二磺酸[L1(H)2=Anthraq-uinone-2,6-disulfonic acid]合成了2,6-蒽二磺酸二钠盐(L1(Na)2),将其钠盐分别与乙酸锌、乙酸镍和4,4-联吡啶(L2)作用合成了两种新型配合物;通过元素分析,红外光谱等方法对配合物的组成、结构进行了表征,确定配合物的组成是[L1Zn(L2)2H2O]H2O、[L1Ni(L2)2H2O]H2O。并研究了两种配合物的热分解性质和荧光性质,研究结果表明配合物[L1Zn(L2)2H2O]H2O具有荧光性质。

Sulfonic acid complexes can be used as potential liquid crystal and nonlinear optical materials. Under the appropriate reaction conditions, the sulfonic acid materials can also form into specific functional complexes. The anthraquinonc-2,6-disulfonic acid disodium salt was prepared from anthraq-uinone-2,6-disulfonic acid [L1 （H）2-anthraq-uinone-2,6-disulfonic acid], and then with using this complex and zinc acetate, nickel acetate and 4,4-bipyridine, two ternary complexes [L1Zn（L1H2O]H2O] and [L1Ni（L2）2H2O]H2O were synthesized. Their compositions and structures were characterized by elemental analysis, IR and etc. The thermal decomposition and fluorescence of these two complexes had been studied. The results showed that the complex [L1Zn（L2）2H2O]H2O] had fluorescence properties.
