| 摘 要： | 以4-苯甲酰吡啶、吩噁嗪和9,9-二甲基吖啶为原料,合成了两种蓝色磷光主体材料:(2-溴-5-吩噁嗪-10-基)苯基](吡啶-4-基)甲酮(BPPPM),2-溴-5-(9,9-二甲基-9H-吖啶-10-基)苯基](吡啶-4-基)甲酮(BDPPM)。并用~1H NMR、~(13)C NMR和元素分析对其结构进行了表征,研究了它们的光电性质和热性质。结果表明,BPPPM和BDPPM的光学带隙(Eg)分别为3.31和2.64 e V;它们的发射峰分别位于405和435 nm,发深蓝和蓝色荧光;它们均具有较高的三线态能级(2.70,2.65e V),可与蓝色磷光客体材料FIrpic(2.65e V)的三线态能级相匹配;它们均具有匹配的HOMO(-5.45、-5.35e V)与LUMO能级(-2.14、-2.82e V),且其HOMO、LUMO轨道的电子云分离突出,具有良好的双极性质;此外它们均具有较好的热稳定性和成膜性。

| Abstract: | Two blue phosphorescent host materials 2-bromo-5-(10-phenoxazine) phenyl-4-pyridone (BPPPM), 2-bromo-5-(10- (9,9-dimethyl) acridinium) phenyl-4-pyridone (BDPPM) based on 4-benzoylpyridine, phenoxazine and 9,9-dimethylacridine were synthesized. The structures of BPPPM and BDPPM were characterized by 1H NMR, 13C NMR and elemental analysis. The photophysical, electrochemical and thermal properties were systematically investigated. The results show that the optical bandgaps (Eg) of BPPPM and BDPPM were 3.31 and 2.64 eV, respectively; their fluorescence emission peaks are deep blue fluorescence at 405 nm and blue fluorescence at 435 nm. Both BPPPM and BDPPM had high triplet energy levels (2.70, 2.65 eV), which matches the triplet level of the blue phosphorescent guest material FIrpic (2.65 eV). Both BPPPM and BDPPM have a very suitable HOMO (-5.45, -5.35 eV) and LUMO level (-2.14 , -2.82 eV) with a small degree of spatial overlap between the HOMO and LUMO. And they have good bipolar properties. In addition, they all have good thermal stability and film-forming properties. |
