Pendant selenium-containing maleimide polymers with different selenium contents are synthesized via a radical copolymerization of styrene and N-butylmaleimide phenyl selenide. The polymer structures are characterized by nuclear magnetic resonance, gel permeation chromatography, Fourier transform infrared spectroscopy, ultraviolet-visible spectroscopy, and scanning electron microscopy with an energy-dispersive spectrometer, which results in the desired structures and selenium contents. The refractive indices of the polymers, which change as a function of different contents of selenium and oxidative stimuli by H O or O , are investigated. Finally, a photonic crystal (PC) is prepared based on the selenium-containing polymer. The visible color changes of the PC are investigated as a function of different concentrations and contact times of O .
通过苯乙烯与N-丁基马来酰亚胺苯基硒的自由基共聚反应合成了具有不同硒含量的含硒马来酰亚胺聚合物。通过核磁共振、凝胶渗透色谱、傅里叶变换红外光谱、紫外可见光谱以及配备能谱仪的扫描电子显微镜对聚合物结构进行了表征，得到了所需的结构和硒含量。研究了聚合物的折射率，其随硒含量以及过氧化氢或氧气的氧化刺激而变化。最后，基于含硒聚合物制备了光子晶体（PC）。研究了光子晶体随氧气不同浓度和接触时间的可见光颜色变化。
