摘要
以菲醌、对硝基苯甲醛、对甲氧基苯甲醛和三苯胺为主要原料,合成了两种新型菲并咪唑衍生物2-(4-(4'-甲氧基苯基亚甲基氨基)苯基)菲并咪唑(MPPI)和2-(4-(4'-N,N-二苯基氨基苯基亚甲基氨基)苯基)菲并咪唑(DPAPPI)。采用FTIR和1H NMR等方法表征了这两种化合物的结构,研究了化合物的紫外吸收光谱、荧光光谱、热稳定性和电化学性能。研究结果表明,MPPI和DPAPPI在二甲基甲酰胺(DMF)中的紫外最大吸收峰分别位于374,392 nm处,在DMF溶液中均发出较强的蓝色荧光;MPPI和DPAPPI的HOMO能级分别为-5.30,-5.14 eV,热分解温度分别为370,391℃,表明MPPI和DPAPPI均具有较好的空穴传输性能和优异的热稳定性,有望作为具有空穴传输性能的蓝光材料应用于发光器件中,是潜在的多功能有机电致发光材料。
Two novel phenanthroimidazole derivatives of 2-(4-(4′-methoxyphenylmethyleneamino) phenyl) phenanthroimidazole(MPPI)and 2-(4-(4′-N,N-diphenylaminophenylmethyleneamino)phenyl) phenanthroimidazole(DPAPPI) were synthesized from phenanthrenequinone,p-nitrobenzaldehyde,p-methoxybenzaldehyde and triphenylamine.The two compounds were characterized by means of FTIR,1H NMR,UV-Vis spectrum and fluorescence spectrum.Their cyclic volt-ampere curves and TG curves were studied.The results showed that the thermal stability of both MPPI and DPAPPI was good.The maximum UV absorption peaks of MPPI and DPAPPI were at 374 nm and 392 nm,respectively,and their dimethylformamide solutions emitted blue fluorescence.The TG curves indicated that their thermal?decomposition?temperatures were at 370 ℃ for MPPI and 391 ℃ for DPAPPI.They could be used as blue light-emitting and hole transport materials.
