以邻菲罗啉和乙酰水杨酸为配体通过溶液共沉淀法合成了铕的配合物Eu(aspirin)3phen,并将铕的配合物掺杂在聚苯乙烯的有机溶液中,利用多孔阳极氧化铝(AAO)模板浸润法制备了荧光聚苯乙烯纳米管/线阵列。通过扫描电子显微镜(SEM),透射电子显微镜(TEM)研究了荧光纳米管/线的形貌和结构。通过红外光谱分析了配合物在聚苯乙烯中的分布方式以及配合物与聚苯乙烯的相互作用,并初步探讨了荧光纳米管/线的生长机制。利用荧光光谱研究了铕配合物及荧光纳米管/线的荧光发光性质。扫描电镜测试结果表明所制得的一维荧光纳米管/线阵列排列规整,直径与AAO模板的孔径一致。透射电镜测试表征了纳米管的管状结构,并证明了铕配合物的存在。红外光谱显示稀土配合物颗粒嵌在聚合物中,与聚合物基质以物理方式相结合。荧光光谱测试表明了稀土配合物具有优良的发光特性。经掺杂制得的荧光聚苯乙烯纳米管/线仍然保持了良好的发光性质,且纳米管阵列的荧光强度随配合物的掺杂含量变化而变化。
Eu (aspirin) 3phen (europium) complex was synthesized by solution coprecipitation method using phenanthroline and acetylsalicylic acid as ligands. The europium complex was doped into the organic solution of polystyrene, Fluorescent polystyrene nanotubes / wire arrays were prepared by using an alumina (AAO) template infiltration method. The morphology and structure of the fluorescent nanotube / wire were investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The distribution of the complex in polystyrene and the interaction between the complex and polystyrene were analyzed by infrared spectroscopy. The growth mechanism of the fluorescent nanotube / wire was also discussed. Fluorescence spectroscopy was used to study the fluorescence emission properties of europium complexes and fluorescent nano-tubes / wires. Scanning electron microscopy results showed that the prepared one-dimensional fluorescent nanotube / linear array arranged regularly, the diameter and AAO template aperture consistent. Transmission electron microscopy characterization of the tubular structure of nanotubes, and proved the presence of europium complexes. Infrared spectroscopy shows that the rare earth complex particles are embedded in the polymer and are physically combined with the polymer matrix. Fluorescence spectroscopy showed that rare earth complexes have excellent luminescence properties. Fluorescent polystyrene nanotubes prepared by doping still maintain good luminescence properties, and the fluorescence intensity of nanotube arrays changes with the doping content of the complexes.
