【摘要】 共轭高聚物荧光性能的研究已成为当今的研究热点,尤其对于有一定限制的蓝色发光材料。这一波段的发光对于全色显示是不可缺少的,因此选择适当的单体和聚合方法,合成既具有优良发光性能又能在此波段发光的共轭聚合物并对其进行研究,具有重要的理论意义和广阔的应用前景。本文以对苯二胺与乙二醛、己二胺缩聚合成了几种不同配比的局部共轭聚希夫碱PHGP,通过红外光谱、紫外光谱、元素分析、分子量测定对其进行了表征。此外,缩聚物在甲酸中可完全溶解,故对其液态荧光性能进行了研究,结果发现,PHGP是既能辐射强荧光,又易于加工处理的蓝光区发光材料。更多还原

【Abstract】 Synthesis and chemical, physical, fluorescence properties of conjugated copolymers are the focus of studies in recent years. Especially, they are used as blue luminescence and electroluminescence materials. At the same time, the blue luminescence is essential to all luminescence. So, synthesis of blue luminescence materials has important theory value and promising prospect. The local πconjugated Schiff base type copolymers(PHGP) with different molar ratio HDA/PPD are synthesized by polycondensation of 1,4diaminobenzene and 1,6hexamethyle amine with glyoxal. The fluorescence of these condensed polymers in liquid state has been investigated. It is found that these condensed polymers can exhibit strong blue fluorescence and are easily treated.更多还原
