【摘要】 制备了有机电致发光材料1,3-二[(4′-特丁基苯基)-(1″,3″-噁二唑-5)]-苯(以下简写作OXD-7),通过核磁共振光谱、红外光谱对其结构进行了表征。利用紫外可见吸收光谱、荧光光谱和循环伏安法等研究了其最高被占用分子轨道(HOMO)及最低空余分子轨道(LUMO)能级及发光性能。OXD-7的HOMO能级为5.24 eV,LUMO能级为1.69 eV。OXD-7在306 nm波长处有一吸收峰。采用300 nm的紫外光激发,荧光发射峰值波长为366.6 nm。更多还原

【Abstract】 An electroluminescent organic compound,namely,1,3-bis[(4′-tert-butylphenyl)-(1,3-oxadiazol-5yl)]-benzene(which is abbreviated as OXD-7 hereafter),was synthesized,and its structure was characterised by the nuclear magnetic resonance spectrometry and infrared spectrometry.The energy levels of the highest occupied molecular orbital(HOMO) and the lowest unoccupied molecular orbital(LUMO) and also the luminescent properties of OXD-7 were studied by the UV-VIS absorption spectrometry,fluorescence spectrometry and cyclic voltammetry.The energy level of HOMO was found to be 5.24 eV and the energy level of LUMO to be 1.69 eV.An absorption maxima of OXD-7 was found at 306 nm.When it was excited at 300 nm,wavelength of the emission spectrum was found at 366.6 nm.更多还原
