好研究的

By dehydrochlorination reaction the poly[(2-methoxyl-5-octyloxy)phenylene vinylene] is synthesized and the material"s structure is characterized by nuclear magnetic resonance spectroscopy, infrared absorption spectrum, ultraviolet and visible spectrophotometry. At the meantime, the fluorescence spectrum is measured and the mechanism of fluorescence occurring is analyzed. Thermal Gravimetric Analyzer"s results show that the MO-PPV"s thermal stability is fine. Also the experiment of resolvable property indicates that the MO-PPV can well dissolve in chloroform. Through analyzing the film"s surface by Metaloscope and Atomic Force Microscope, the good filming is found.

通过脱氯缩合法合成了聚(2-甲氧基-5-辛氧基)对苯乙炔，并分别用核磁共振波谱法、红外吸收光谱法、紫外-可见分光光度法等对其进行了结构表征；测量了样品的荧光光谱，分析了荧光产生的机理；热失重仪分析了材料的热稳定性，研究表明MO-PPV材料具有良好的热稳定性；溶解性实验发现材料在氯仿中溶解性较好；金相显微镜和原子力显微镜研究了薄膜的表面形貌，发现该材料的成膜性良好；材料的导电性研究表明，固体材料在掺杂下才可以表现出导电特性，而配成溶液的材料导电性因溶剂的不同而不同，并随溶解时间的长短发生变化。
