【摘要】 将8-羟基喹哪啶-丙烯酸-镓( )的三元配合物单体与苯乙烯共聚后得到一种含镓( )的共聚物。通过红外光谱、元素分析、紫外光谱、广角X射线衍射等方法对三元配合物和共聚物的组成进行了表征。测试共聚物的荧光光谱,发现共聚物的氯仿溶液在493nm处能发出较强的荧光,共聚物膜在473nm处能光致发光。DSC分析表明共聚物具有良好的耐热性。广角X射线衍射结果表明共聚物为非晶结构。更多还原

【Abstract】 A new copolymer of 8-hydroxyquinaldine gallium acrylate and styrene was prepared. The composition and properties of the copolymer were characterized by FT-IR, UV, DSC, WAXD and fluorescence spectrum. A strong blue-green photoluminescence, with 493 nm maximum wavelength, was observed for the copolymer/CHCl₃ solution, the fluorescence intensity enhances with increase of the concentration. The film of the copolymer emits a photoluminescence at 473 nm maximum wavelength. The copolymer is soluble in chloroform, acetone, DMF in 25 ℃, so it can be easier to prepare electroluminescent device by spin-coat technology. DSC analysis shows that Tg of copolymer increases 27 ℃ than that of PS, it shows the copolymer has better thermal stability than PS. The results of WAXD indicate that the copolymer is a kind of uncrystalline compound.更多还原
