摘要
以Witig反应的方法,分别合成了五种聚对苯撑乙烯(PPV)齐聚物,并用红外光谱、核磁共振、紫外可见光谱及荧光光谱对所得齐聚物进行了测试和表征,发现它们的溶解性都有所改善,紫外可见光谱均向红移。
Five poly(phenylene vinylene)'s oligomers, PPPN,OMePPV,2,4OMePPV, OEtPPV and NO2PPV were synthesized by Wittig reaction and characterized by 1HNMR, FTIR, UVvis absorption and fluorescence spectra respectively. The results showed that the solubility were improved and the maximum position of absorption in UVvis and emission spectra of all oligomers were shifted to longer wavelength.
