采用循环伏安(CV)法结合紫外-可见(UV-Vis)吸收光谱表征了4种新型电致发光材料三芳胺聚合物TPD(PTPD)的能带结构,并对引入的基团及分子结构对其能带结构的影响进行了探讨。结果表明,从聚合物TPD和小分子TPD的UV-VIS吸收光谱的最大吸收来看,聚合后TPD的能带结构没有太大的改变。从循环伏安图看出,材料的具有较好电化学稳定性。并制成了ITO(氧化铟锡)/PTPD/Alq3(8-羟基喹啉铝)/Mg:Ag异质结电致发光器件,与典型的ITO/TPD/Alq3/Mg:Ag器件进行了比较,研究发现其器件的稳定性有的明显提高。
Cyclic voltammetry (CV) and UV-Vis absorption spectra were used to characterize the energy band structures of four novel phosphorescent triazine polymers TPD (PTPD). The effects of the introduced groups and molecular structures The influence of its band structure is discussed. The results show that from the maximum absorption of UV-VIS of TPD and TPD, there is not much change in the band structure of TPD after polymerization. Cyclic voltammograms seen, the material has good electrochemical stability. And an ITO (Indium Tin Oxide) / PTPD / Alq3 (8-hydroxyquinoline aluminum) / Mg: Ag heterojunction electroluminescent device was fabricated and compared with a typical ITO / TPD / Alq3 / Mg: Ag device , The research found that the stability of the device and some significantly improved.
