【摘要】 以Grignard反应和脱水缩聚的方法合成了一种含恶二唑基团的聚芴型电致发光材料,通过紫外-可见光谱和电化学法得到该材料的能带隙约为2.99 eV,最低未占有分子轨道能级约为2.95 eV,其有望成为应用在蓝色电致发光器件中的高分子电子传输材料。更多还原

【Abstract】 Polyfluorene-based electroluminescent material containing oxadiazole groups was synthesized by grignard reaction and dehydration condensation method.The band gap and lowest unoccupied molecular orbital energy,which were about 2.99 eV and 2.95 eV respectively,were achieved by UV-Vis spectra and electrochemical method.This proved that the electroluminescent material could be expected to become a kind of macromolecule electron transmission material used for blue electroluminescent apparatus.更多还原
