对有机聚合物发光材料的研究越来越受到人们的重视,并且有机聚合物具有很多优点,如:良好的加工性能、成膜性能。本论文合成的聚吡咯甲烷,通过紫外光谱分析可知,在200~400nm左右有明显的光学吸收;通过荧光光谱分析可知,以二氯甲烷作溶剂合成的聚吡咯甲烷激发波长在370nm,发射波长在460nm左右;以1,4-二氧六环作溶剂合成的聚吡咯甲烷激发波长在335nm,发射波长在470nm左右。聚吡咯甲烷是一种典型的发蓝色光的材料。但是在不同溶剂中,样品的发射波长和荧光强度差别比较明显;通过X射线衍射谱分析可知该样品的聚集态是完全非晶态。

The research of organic polymer luminescent material more and more get people's attention, and organic polymer has many advantages, such as: good processing performance, film forming performance. This paper synthesized polypyrrole methane by ultraviolet spectrum analysis shows that in 200 ~ 400 nm has obvious optical absorption; By fluorescence spectrum analysis shows that with dichloromethane as solvent to synthesize polypyrrole excitation wavelength at 370 nm, methane emission wavelength at around 460 nm; With 1, 4 - dioxane as solvent to synthesize the polypyrrole excitation wavelength at 335 nm, methane emission peak at about 470 nm. Polypyrrole methane is a kind of typical blue color material. But in different solvents, emission wavelength and fluorescence intensity of samples are the obvious difference; Through X-ray diffraction spectrum analysis on the state of aggregation is completely amorphous sample.对有机聚合物发光材料的研究越来越受到人们的重视,并且有机聚合物具有很多优点,如:良好的加工性能、成膜性能。本论文合成的聚吡咯甲烷,通过紫外光谱分析可知,在200~400nm左右有明显的光学吸收;通过荧光光谱分析可知,以二氯甲烷作溶剂合成的聚吡咯甲烷激发波长在370nm,发射波长在460nm左右;以1,4-二氧六环作溶剂合成的聚吡咯甲烷激发波长在335nm,发射波长在470nm左右。聚吡咯甲烷是一种典型的发蓝色光的材料。但是在不同溶剂中,样品的发射波长和荧光强度差别比较明显;通过X射线衍射谱分析可知该样品的聚集态是完全非晶态。

Research on organic polymer light-emitting materials have been paid more and more attention, and the organic polymer has many advantages, such as: the film-forming performance, good processing performance. In this paper, the synthesis of polypyrrole methane, by ultraviolet spectroscopy analysis, significant optical absorption at about 200~400nm; the fluorescence spectrum analysis, using dichloromethane as solvent to synthesize polypyrrole methane excitation at the wavelength of 370nm, emission wavelength of around 460nm; to 1,4- two oxygen ring six as solvent to synthesize polypyrrole methane excitation wavelength in 335nm at about 470nm, emission wavelength. Polypyrrole methane is a typical blue light emitting materials. But in different solvents, emission wavelength and fluorescence intensity difference samples is obvious; the X ray diffraction spectrum aggregation analysis indicated that the samples are amorphous.

The research on organic light-emitting polymer materials is paid more and more attention, and organic polymers have many advantages, such as good processing performance, film-forming performance. The polypyrrole methane synthesized in this paper has obvious optical absorption at about 200 ~ 400nm, which can be seen from UV spectral analysis. It can also be found by fluorescence spectroscopy that the methylene chloride synthesized using 1,4 - dioxane has an excitation wavelength of 335nm, and an emission wavelength of about 470nm. Polypyrrole methane is a typical blue-emitting materials. But in different solvents, the emission wavelength and fluorescence intensity of the samples has rather obvious difference. In addition X-ray diffraction analysis shows that the aggregation state of the sample is completely amorphous.
