己酰基吡唑啉酮锌配合物的合成与表征

Synthesis and Characterization of Caproypyrazolone Zinc Complexes

酰基吡唑啉酮配合物在功能材料、金属离子萃取、生物活性等领域应用广泛。以1-苯基-3-甲基-吡唑啉酮-5(PMP)为母体,设计合成出4-己酰基吡唑啉酮(HL),通过4-己酰基吡唑啉酮配体(HL),非水溶剂法与金属Zn盐成功合成金属配合物,应用光学和热学分析检测仪对HL与金属配合物进行性能表征。红外光谱中发现,烯醇羟基已去质子化发生配位,吡唑啉酮环共轭形成大的离域键。热重分析测试表明金属配合物在107℃时开始失去水分子,配合物存在并且应用环境不高于107℃。

The acylpyrazolone complexes are widely used in functional materials, metal ion extraction and biological activities. The 4-hexyl pyra-zolone（HL）is designed and synthesized with the 1-phenyl-3-methylpyrazolinone-5（PMP）as matrix. Through a 4-hexyl pyrazolone ligand（HL）,nonaqueous solvent method and metal salt Zn, the metal complexes are successfully synthesized, and the performance of HL and metal complexes are characterized by optical and thermal analysis tester. In the infrared spectrum, it is found that the enol hydroxyl group has deprotonated and coordinat-ed, and the pyrazolone ring is conjugated to form a large delocalized bond. The thermal weight analysis test shows that the metal complexes begin to lose water molecules at 107℃, and the environmental temperature for the existence and application of complexes is lower than 107 ℃.
