摘要
用三异丙氧基铕与乙酰丙酮、丙烯酸合成铕 -乙酰丙酮 -丙烯酸配合物 [Eu(acac) 2 AA],将其与苯乙烯共聚制得共聚物 (Eu- CO- PS)。用元素分析、IR、UV、DMTA和荧光光谱表征其结构与性质 ,表明共聚物 (Eu- CO- PS)
The copolymer containing europium was prepared by the copolymerization of Eu(Ⅲ) complex with styrene. The fomula of Eu complex can be expressed by Eu(acac) 2AA, where acac=acetyl acetone, AA=acrylic acid. The copolymer was characterized by elemental analysis, FT IR, UV, fluorescence spectrum and DMTA. It is soluble in common organic solvents, such as benzene, chloroform, THF and acetone. The fluorescence spectrum indicates that the copolymer is a sort of materials with good fluorescence property and the higher fluorescence intensity with higher Eu content. The DMTA indicates higher tenacity than PS. It shows that the copolymer has better mechanical property.
