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.
