Synthesis and Fluorescence Characteristics of Rare EarthComplexes of 1,4-bis(3,5-dimethyl-1H-pyrazol-1-yl)phthalazine
【摘要】 该文以1,4-双肼屈嗪和乙酰丙酮为原料分别采用微波、常规法经过环合化反应合成了一种新的双吡唑配体:1,4-双(3,5-二甲基-吡唑)屈嗪,其中微波法产率为59%,常规法产率为63%.通过红外光谱、核磁共振谱和质谱对其结构进行了表征,并对稀土离子Eu3+、Tb3+配合物在不同有机溶剂中的荧光光谱进行了测定和对比.
【Abstract】 A new organic ligand: 1,4-bis(3,5-dimethyl-1H-pyrazol-1-yl) phthalazine had been synthesized by 1,4-bihydrazine-phthalazine and pentane-2,4-dio-ne through the microwave reaction and the normal reaction in ring closure reaction,and its chemical structures was characterized by IR, 1H NMR and MS.The liquid fluorescence characteristics of the Eu3+,Td3+ complexes were studied in different solvents(methanol,ethanol,1,4-dioxine) respectively.
