摘要 采用原位脱氯化氢缩合聚合法制备了聚(2-甲氧基-5-辛氧基)对苯乙炔/二元稀土配合物Eu(phen)2Cl3(PMO-COPV/Eu(phen)2Cl3)杂化材料。红外光谱证实了在Eu(phen)2Cl3表面的包覆层为PMOCOPV。紫外-可见吸收光谱表明与PMOCOPV相比,PMOCOPV/Eu(phen)2Cl3的最大吸收峰发生红移且强度增强。荧光光谱研究表明PMOCOPV/Eu(phen)2Cl3的最大发射波长发生红移且强度增强,荧光寿命得到提高,Eu(phen)2Cl3与PMOCOPV之间形成了光致电子转移体系,使得π电子离域程度增加,导致荧光量子效率提高。 The photoelectric hybrid material poly(2-methoxy-5-octyloxy)-p-phenylene vinylene/Eu(phen)2Cl3(PMOCOPV/Eu(phen)2Cl3) was prepared by a dehydrochlorination in situ polymerization.Results from Fourier transform infrared spectroscopy indicate that PMOCOPV is coated onto the surface of Eu(phen)2Cl3.Compared with PMOCOPV,the absorption of PMOCOPV/Eu(phen)2Cl3 is strengthened,and a red shift of the absorption peak can be clearly observed in the UV-Vis spectrum.Photoluminescence spectroscopy indicates that the maximum emission wavelength of the PMOCOPV/Eu(phen)2Cl3 is red-shifted and intensity of photoluminescence increases in comparasion with PMOCOPV.PMOCOPV/Eu(phen)2Cl3 shows increased fluorescence due to an intermolecular photo-induced charge transfer process.
